SoftEther VPN Ubuntu/Linux Client Configuration behind HTTP Proxy. 11 June 2015 on, SoftEther VPN is one of the alternatives of OpenVPN. The SoftEther Project is maintained by University of Tsukuba. Why not OpenVPN? I started using SoftEther VPN because of the poor performance of OpenVPN over TCP especially when you are behind a http proxy.
The reason for this is OpenVPN's use of single TCP connection. The http proxy load balances the TCP connections so basically you get a poor speed on a single TCP connection as compared to others who are browsing without a VPN and using 6-8 parallel connections. SoftEther can use multiple TCP connections to boost the overall speed. I got a 3x speed boost by using multiple TCP connections ( 32 Mbps Down & 12 Mbps Up ). I used to reside in a university campus where my only access to Internet was through a proxy server which was listening on port 3128. All other ports were blocked. The problem with the Linux VPN client of SoftEther is that it does the minimal that it should do i.e.
Only connecting to the server and setting up a virtual network interface. You will have to configure your routing tables and DNS settings appropriately to make it work properly. I assume that you are having the Domain Name/IP address of a Soft Ether VPN Server( you can get one from ). I will use the vpn613096262.opengw.net:443 for this post. So Lets Start. Download the from SoftEther website for your distribution. Extract the package $ tar -xvf softether-vpnclient-v4.14-9529-beta-2015.02.02-linux-x64-64bit.tar.gz.
Run Make and then run the VPN client. $ cd vpnclient $ make $ sudo./vpnclient start. Run vpncmd, create a new NIC. Select 2 “Management of VPN Client”. Don’t enter anything in the hostname, just press enter, it will take the default value “localhost”. Enter $ VPNCLIENT niccreate se.
Enter $ VPNCLIENT AccountCreate server1. Enter the server’s host name and port in the format: For eg. Vpn613096262.opengw.net:443. Enter the Virtual Hub Name as 'VPNGATE' if you are using.
Vpngate or as configured on the server. Enter the username: 'vpn' for VPNGATE or as configured on the server.
Enter the Virtual Network Adapter name: se. Set the password by. $ VPNCLIENTAccountPasswordSet server1 /PASSWORD:vpn /TYPE:standard.
If you are behind an HTTP Proxy, you need to set the proxy for the account. $ VPNCLIENT AccountProxyHttp server1 /SERVER:202.141. /USERNAME:user /PASSWORD:pass. Connect to the server. $ VPNCLIENT AccountConnect server1. You can check the status of the connection by $ VPNCLIENT accountlist.
You should see Connected in the status field. Now that you are connected, you will need to get the ip address from the server and set the routes appropriately. Getting the IP address.
$ sudo dhclient vpnse (Yes it is “vpnse” not “se”). You can check the alloted ip address by $ ip addr show vpnse. Get the local ip of the VPN server by $ ip neigh It will have the interface vpnse. If you don’t find any entry with vpnse. Try the first or last ip address of your local ip range. If by $ ip addr show vpnse you got that your ip is 10.211.1.7/16, then first ip in the subnet is 10.211.0.1, the last is 10.211.254.254.
For most of the vpngate servers, last ip is the local ip of the vpn server. Now that you have the local ip of the vpn server call it vpnserverlocalip. Now we have to add a route to VPN server via your original gateway, and modify the default route to use the VPN NIC and VPN gateway( vpnserverlocalip ). Before we tweak the routing table, enable ip forward in '/etc/sysctl.conf' by adding line net.ipv4.ipforward=1 to the file and load it by and load it by $ sysctl -p. Now we are going to change the routing table.
To get your default gateway $ route-n. The gateway corresponding to 0.0.0.0 is the default gateway. Now we have default gateway, vpnserverlocalip. We need the remoteip to which vpn client connects to. If you are not behind proxy, get the ip address of the remote vpn server, you can get this by using this and this will be your remoteip. If you are behind proxy, your proxy server address is your remoteip.
Now we are set to setup routing tables, replace the fields appropriately. $ ip route add remoteip via defaultgateway dev wlan0 proto static $ ip route del default $ ip route add default via vpnserverlocalip dev vpnse For my case these commands were $ ip route add 202.141.80.19 via 192.168.1.1 dev wlan0 proto static $ ip route del default $ ip route add default via 10.211.254.254 dev vpnse.
Final step, configure the DNS. $ sudo su $ echo 'nameserver 8.8.8.8' '/etc/resolv.conf' Note - To get back your default routing table i.e. After you disconnect from vpn, restart the network service sudo service network-manager restart The tedious way of doing this is to delete all the routes that you have setup.

It is an Apple iPhone 5 that I want to connect (enable VPN). Originally I had setup my server using these instructions however, when I connected my iPhone and ran a speedtest it was very slow (1MB D/L speeds). Therefore, I wanted to test your config setup to see if I could get better speeds, but I don’t how to connect my iPhone. On the digital ocean setup it was simple to connect my iphone – I just went into Settings on my iPhone and added a VPN connection using L2TP and it worked. So i just want to get to that stage connect to iphone then test speeds. Cimb niaga biz channel. First, the only possible way for connecting iOS to SoftEther is L2TP currently. The speed is limited coz there is only one active link can be made for each device parallelly.
I don’t have any better idea to deal with that. For connecting iOS device to SoftEther Server, you need to enable the L2TP from server side by the management client.
You will be prompted to input the default switch name for L2TP client (should be VPN if you follow the guide). On the client side, it’s quite same like you did before. PS, you cannot do that without GRE support on your server side, like server in Microsoft Azure. The IP address and range is for the virtual network created by SoftEther only. It should not be the same as your network. In fact, I choose 192.168.250.x just for getting avoid of common IP addresses. If you can get the IP from SoftEther, which should be 192.168.250.x, nothing is wrong with the DHCP server setting.
BTW, some settings may block your access to the same computer with a IP from LAN. In your case, you may not able to access 172.16.0.102 from the SoftEther client.
Instead, you can try to navigate 192.168.250.1 instead from client. 192.168.250.1 is the IP address set to SoftEther Server as a virtual IP, which should be accessed by VPN clients.
Thank you very much Mister Allen, it works very smooth. On the client side I get 192.168.250.10 from the virtual dhcp and then I can access samba share 192.168.250.1. Also, is working very well also by real private ip 172.16.0.102 and there are no problems from the LAN, from 100 and 101 samba share is working like before.
What can I say, your tutorial here is VERY GOOD, thank you VERY MUCH from your very fast reply and for the additional explanations! I asked also on Official Softether forums, nobody answered, them support is ZERO. Really appreciated, Best regards, sigma. Me again mister Allen. I deleted option routers 192.168.250.1 on a different server because I want just an access VPN type. The problem is once connected, I can direct access only the server but not the other machines from that network.
Every time the windows clients have to add the route t be able to access all the network resources. Route add 172.16.0.0 mask 255.255.255.0 192.168.250.1 (just an example) I tried different solutions to push routes in the softether configuration even in dnsmasq configuration as well. Nothing works from what I’ve tested, no effect at all. There is a “Static routing table to push” very clear option on SecureNAT configuration which probably works but I DON’T WANT to use SecureNAT instead of local bridge Any advise is highly appreciated.
Best regards, sigma. I have set up softether vpn with virtual hub that I am able to use to bypass my ISP portal for free internet using the “vpn over DNS” feature. This works fine sometimes but the problem is that I mostly need to connect to a working internet connection and then disconnect it before I connect to the ISP internet that I want to bypass.
A friend has a similar set up which works fine, he is able to connect straight away anytime he wants to, he does not want to enlighten me on what I am doing wrong. I wish there’s a way you can take a look at my set up and see if there’s something I’m doing wrong. Everything works when I connect with a few minutes interval of a connection but after about 5 minutes of disconnection, if I try to connect again, I get “protocol Error”, if this happens, I connect to a working internet connection and then disconnect and connect directly to my ISP blocked connection before the connection works. I really need help with this, I set up the server exactly as you outlined above. I have several problems with a new installation on centos 7.1 minimal this time. On centos 6 was working like a charm but on centos7 can’t make HDCP server to work.
It is just not starting because in file: /etc/sysconfig/dhcpd you can not put anymore DHCPDARGS=tapvpn. First time I ignore it, then I have followed the instructions provided in file to edit /etc/systemd/system/dhcpd.service where i put tapvpn as interface name.

In centos 7 if you open the file: /etc/sysconfig/dhcpd you will see some additional explanations which says that anything you want to add to this file like DHCPDARGS=tapvpn should be added into a different file: you have already written all the commands but are commented #. It is totally bullshit, it is not working.
Stick to the old method which is explained into this tutorial and put DHCPDARGS=tapvpn at the end of the file. In a normal centos 7 install should work. Connect to your server by server manager and create a local bridge adapter called vpn (prefix tap will be added automatically). You may delete my previous post, it was a mistake and it is not related to this tutorial. Best regards.
I followed everything carefully. Softether works fine as I am able to connect to the server from the client machine but I am not being issued an IP and when I run service vpnserver restart to start the Softether on the server side this is the output I get. root@sv3 # service vpnserver restart Stopping the SoftEther VPN Server service SoftEther VPN Server service has been stopped.
The SoftEther VPN Server service has been started. Starting dhcpd: FAILED dnsdomainname: Unknown host dnsdomainname: Unknown host dnsdomainname: Unknown host Starting dnsmasq: dnsmasq: failed to create listening socket: Address already in use FAILED.

4.2.1 VPN Client Manager SoftEther VPN Client Manager is a utility with a Windows-supported graphical user interface (GUI) that allows the user to operate SoftEther VPN Client. Normally, the end user uses VPN Client Manager to operate VPN Client.
VPN Client Manager allows the user to easily operate nearly all VPN Client operations by selecting menu items and entering required information in the GUI windows in the same manner as a conventional Windows application. Therefore, even users without much knowledge of VPN technologies can quickly operate VPN Client. VPN Client Manager also enables control of VPN Client services from local computers as well as from remote computers. In this case, you must configure the destination VPN Client setting to allow for a remote connection.
In this way, the administrator can remotely control the VPN Client service installed in a computer at a remote location. You can also operate the Linux version of VPN Client using VPN Client Manager.
This manual does not describe in detail the operating procedure for operating VPN Client Manager while connected to a remote computer, but you can use the method for operating VPN Client Manager while connected to a local computer in almost the same way. VPN Client Manager is installed at the same time as the Windows version of VPN Client.
VPN Client Manager. Command Line Management Utility (vpncmd) SoftEther VPN Client Manager is a GUI application, but you can use vpncmd as a utility that performs the same operations from the command line. For more information about vpncmd, please refer to and. You can easily automate management by operating and controlling VPN Client using vpncmd.
For example, it is possible to automatically connect to a specified VPN server at a specified time. With vpncmd, normally all operations that can be performed with VPN Client Manager can be performed using the command line. In this chapter, it is assumed that VPN Client Manager is used to operate VPN Client. For more information about operating VPN Client using vpncmd, please refer to. Controlling VPN Client Using the Command Line Management Utility (vpncmd). 4.2.3 Task Tray Icon When SoftEther VPN Client is installed, the SoftEther VPN Client icon is placed on the Windows task tray in the taskbar.
The user can use this icon to quickly operate VPN Client Manager without having to open the window. SoftEther VPN Client Task Tray Icon. In addition, the display of the task tray icon indicates the current VPN connection status. If the icon is grayed out, this indicates that currently there is no VPN communication. If the icon is highlighted and is rotating quickly, this indicates that the software is connecting to VPN Server.
