I downloaded the softether vpn client for my xubuntu 14.04 (32 bit) but after that I am unable to proceed further.

And they also don't have the installation guide for vpnclient ( they have for server).

So please guide me in how to successfully set up the softether vpnclient?

Thank you.

How to set up SoftEther VPN Client under Linux: Via vpngate.net

Client Set Up Procedure Under Linux

  1. Download VPN client from softether.org
    • My platform is Debian 7 X64
  2. compile vpn client in your platform in the un-compressed vpn client directory
    • just type "make" and accept all the license agreements and you should be O.K.
  3. start the vpnclient service as root
    • sudo ./vpnclient start
  4. connect to local vpnclient using "vpncmd" (normal user mode, no root privilege needed"), create a local virtual NIC.

vpncmd

VPN Client>remoteenable
RemoteEnable command - Allow Remote Management of VPN Client Service
The command completed successfully.

VPN Client>niccreate
NicCreate command - Create New Virtual Network Adapter
Virtual Network Adapter Name: se

The command completed successfully.

The command completed successfully.
  1. go to "vpngate.net", find an appropriate vpn server

  2. Set up a vpn account in vpncmd.

I export the vpn account config file below, you can tailor it for your need.

VPN Client>accountimport 
AccountImport command - Import VPN Connection Setting
Import Source File Name: /home/luke/japan0.vpn

The VPN Connection Setting "japan0" was imported.
The command completed successfully.

  1. Now the vpn account is connected. Under Linux, the routing table is not modified automatically as under Windows. We need to manually tweak routing information to make SoftEther VPN work.
    • The key point here is : DHCP the virtual NIC to obtain virtual IP from VPN Server; add a route to VPN server via your original normal gateway, and modify the default route to use the VPN NIC and VPN gateway( the virtual address).

Before we tweak the routing table, enable ip forward in "/etc/sysctl.conf"

net.ipv4.ip_forward=1

and load it by:

sysctl -p 

Now we are going to change the routing table.

luke@luke-debian:~$ ip addr show vpn_se
10: vpn_se: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500
    link/ether 00:ac:dd:07:19:70 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::2ac:ddff:fe07:1970/64 scope link 
       valid_lft forever preferred_lft forever
luke@luke-debian:~$ sudo dhclient vpn_se
luke@luke-debian:~$ ip addr show vpn_se
10: vpn_se: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500
    link/ether 00:ac:dd:07:19:70 brd ff:ff:ff:ff:ff:ff
    inet 10.211.1.63/16 brd 10.211.255.255 scope global vpn_se
    inet6 fe80::2ac:ddff:fe07:1970/64 scope link 
       valid_lft forever preferred_lft forever
luke@luke-debian:~$ ip neigh
192.168.100.1 dev wlan0 lladdr 00:1c:f0:4d:a0:a8 REACHABLE
10.211.254.254 dev vpn_se lladdr 00:ac:50:16:c8:27 REACHABLE
172.31.224.99 dev vpn_se lladdr 00:ae:df:62:34:d9 STALE

After the dhcp process, vpn_se acquires an virtual ip address "inet 10.211.1.63/16" from vpn server, and we can see from "ip neigh" that the virtual IP address of vpn server is "10.211.254.254".

Now we are going to add two routes to facilitate all traffic through new create VPN. My laptop is connected to router 192.168.100.1 via wireless "wlan0".

$ ip route
default via 192.168.100.1 dev wlan0 
10.211.0.0/16 dev vpn_se  proto kernel  scope link  src 10.211.1.63 
169.254.0.0/16 dev wlan0  scope link  metric 1000 
172.16.125.0/24 dev vmnet1  proto kernel  scope link  src 172.16.125.1 
192.168.86.0/24 dev vmnet8  proto kernel  scope link  src 192.168.86.1 
192.168.100.0/24 dev wlan0  proto kernel  scope link  src 192.168.100.101 
$ sudo ip route add 222.228.120.128/32 via 192.168.100.1 dev wlan0
$ sudo ip route del default
$ sudo ip route add default via 10.211.254.254 dev vpn_se
$ ip route show
default via 10.211.254.254 dev vpn_se 
10.211.0.0/16 dev vpn_se  proto kernel  scope link  src 10.211.1.63 
192.168.100.0/24 dev wlan0  proto kernel  scope link  src 192.168.100.101 
222.228.120.128 via 192.168.100.1 dev wlan0

After the route is set up correctly, we can see the default routing has been directed to VPN tunnel. We can confirm this from the output of "traceroute" since all hops could not be displayed any more.

A bash script will save lots of typing.

$ cat /etc/network/interfaces 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto-hotplug vpn_se
iface vpn_se inet dhcp



$ cat route.sh

#!/bin/bash
if [ "x$2" == "x" ]; 
then
  echo "vpn server ip missing!  ./route.sh add/del vpn_server_ip " 

else

 case "$1" in

 add)



 # restore default route to home network
 ip route delete default
 ip route add default via 192.168.100.1 dev wlan0

 # obtain ip address for vpn_se

 ifup vpn_se


 # add route to vpn server

 ip route add $2/32 via 192.168.100.1 dev wlan0
 ip route delete default
 ip route add default via 10.211.254.254 dev vpn_se

Even I faced the same problem but following step by step on this reference made my day. Inside .vpn file small changes need to be made, like, your account information and remote server you wish to route the traffic from and to. Choose from many remote server and create account by visiting this page. Adding my custom server configuration for clarification sake.

declare root
{
 bool CheckServerCert false
 uint64 CreateDateTime 0
 uint64 LastConnectDateTime 0
 bool StartupAccount false
 uint64 UpdateDateTime 0

  declare ClientAuth
 {
  uint AuthType 1
  string Username fastssh.com-server-sp
 }
 declare ClientOption
 {
  string AccountName se-singapore
  uint AdditionalConnectionInterval 1
  uint ConnectionDisconnectSpan 0
  string DeviceName se
  bool DisableQoS false
  bool HalfConnection false
  bool HideNicInfoWindow false
  bool HideStatusWindow false
  string Hostname se-singapore.serverip.co
  string HubName FastSSH
  uint MaxConnection 1
  bool NoRoutingTracking false
  bool NoTls1 false
  bool NoUdpAcceleration false
  uint NumRetry 4294967295
  uint Port 443
  uint PortUDP 0
  string ProxyName $
  byte ProxyPassword $
  uint ProxyPort 0
  uint ProxyType 0
  string ProxyUsername $
  bool RequireBridgeRoutingMode false
  bool RequireMonitorMode false
  uint RetryInterval 15
  bool UseCompress false
  bool UseEncrypt true
 }
}

Hope this helps!!
