Processing
Step to install and run SoftEther
Configure Port Forwarding
In SME Server Manager set the following rules under Security -> Port Forwarding:
| Protocol | Source Port(s) | Destination Host IP Address | Destination Port(s) | Allow Hosts | Rule Comment | Action |
| TCP | 1194 | localhost | 1194 | SoftEther OpenVPN | ||
| TCP | 5555 | localhost | 5555 | SoftEther Management | ||
| UDP | 1194 | localhost | 1194 | SoftEther OpenVPN | ||
| UDP | 500 | localhost | 500 | SoftEther SoftEther L2TP/IPSec | ||
| UDP | 1701 | localhost | 1701 | SoftEther SoftEther L2TP/IPSec | ||
| UDP | 4500 | localhost | 4500 | SoftEther SoftEther L2TP/IPSec |
or you can manually add the portforwarding rules:
db portforward_tcp set 1194 forward Comment 'SoftEther OpenVPN' DestHost localhost DestPort 1194 AllowHosts ' ' DenyHosts ' ' db portforward_tcp set 5555 forward Comment 'SoftEther Management' DestHost localhost DestPort 5555 AllowHosts ' ' DenyHosts ' ' db portforward_udp set 1194 forward Comment 'SoftEther OpenVPN' DestHost localhost DestPort 1194 AllowHosts ' ' DenyHosts ' ' db portforward_udp set 500 forward Comment 'SoftEther SoftEther L2TP/IPSec' DestHost localhost DestPort 500 AllowHosts ' ' DenyHosts ' ' db portforward_udp set 1701 forward Comment 'SoftEther SoftEther L2TP/IPSec' DestHost localhost DestPort 1701 AllowHosts ' ' DenyHosts ' ' db portforward_udp set 4500 forward Comment 'SoftEther SoftEther L2TP/IPSec' DestHost localhost DestPort 4500 AllowHosts ' ' DenyHosts ' ' signal-event portforwarding-update

Download And Install Bridging
More info is required and needs to be explained why the bridging is needed, if at all.
For SME 9.x 32 Bits
rpm -i http://mirror.contribs.org/releases/9.2/smecontribs/i386/RPMS/smeserver-bridge-interface-0.2-1.el6.sme.noarch.rpm --nodeps signal-event post-upgrade; signal-event reboot
For SME 9.x 64 Bits
rpm -i http://mirror.contribs.org/releases/9.2/smecontribs/x86_64/RPMS/smeserver-bridge-interface-0.2-1.el6.sme.noarch.rpm --nodeps signal-event post-upgrade; signal-event reboot
Configure Bridging and restart

Test With Windows
Create VPn Connection
Set Internet Address and Destination Name, clic do not connect now and Next
Set User Name and Password
Set Property On Your VPN Connection
Choose VPN Network Type and clic on Advanced Settings
Type Your Pre-Shared Key
Make A Connection and Check State
You can now access your samba ressources !
Radius authentication
First set the Radius server credentials (thus the info of SME Server itself)
host: localhost UDP port 1812 key: default shared secret that can be found with: cat /etc/radiusclient-ng/servers
Secondly create a 'passthrough user' with the username of '*', set Auth Type to Radius and enable security policy. The default policy enables allows all SME Server users.
If you previously created SME Server users manually, you can delete these so there is ONLY one user called '*'
All SME Server users should now be able to create a VPN connection. Since Softether VPN is not 'integrated' yet into the db and templating system, one does not need to enable VPN access on SME Server user accounts. This option in Server Manager will be ignored by Softether VPN. By default when authenticating against the SME Server Radius server all users will be able to create a VPN connection.
TODO
Create a rpm with softether vpnserver RTM
Create a rpm with a bridge for softether (The smeserver-bridge-interface can do this)
Use SME Radius
Hints and tips
- Using the native MS-SSTP VPN possibility on windows, one must use not just the username but username@virtualhub_name
