Softether in jail
Posted: 19 Nov 2016 23:27
I installed Softether in a jail using the following guide (https://forums.freenas.org/index.php?th ... vpn.47395/).
I get it installed perfectly fine, but I have an issue creating a "local bridge". This local bridge connects my VPN Hub to my physical network interface.
After doing some research, I discovered that Softether has some problems with FreeBSD and it's physical network interface (see https://www.softether.org/4-docs/1-manu ... al_Bridges point 3.6.9 and 3.6.11).
Therefore, I decided to create a tap interface, which will connect to my VPN Hub. I also created a bridge interface, to connect the tap interface to my physical network adapter.
My network looks like this.
The output of ifconfig is.
When looking at my local bridge in the Softether commandline utility, it is either offline or gives me an error status.
From the ifconfig output, I notice that my tap0 interface has no carrier, which I assume is the problem. After doing some more research, apparently it becomes active when an application is tied to the tap0 interface. I can't figure out how to do this though.
Does anybody have any suggestions?
