Hi,
I have a need to run Softether on a firewall that has 3 networks, public, DMZ and OSS
The firewall I am currently using is ipFire - I managed to create an addon and install it correctly ( "check" is not complaining )

The purpose of softether is to allow VPN access to OSS network
I have created the hub,users and local bridge
DHCP is provided by 172.31.255.2 on OSS network

But it is not working
How can I configure softether to allow VPN to OSS netowork when it is running on the firewall ?

Note
With softether installed on one of the OSS servers ( e.g 172.31.255.2) it works beautifully by just configuring ipFire to forward port 992 to it

Here are some details:
Pubilc IP: 10.10.10.3
OSS: 172..31.255.1
DMZ: 172.31.248.1

If I NAT port 992 to 172.31.255.1 , I am getting
"
Several VPN Servers on the same IP address. You can specify the destination server's private IP or hostname concretely such as "Global IP address or host name/192.168.x.x". Or if a NAT is used on the server's side, configure the NAT to open, relay or transfer appropriate ports. (code 131)"
