Softether in jail

Post by captainkent »

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.

Code: Select all

em0 (Physical Network) <-> bridge0 <-> tap0 <-> Softether Hub
The output of ifconfig is.

Code: Select all

em0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 1500
        options=40098<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,VLAN_HWTSO>

                ifmaxaddr 0 port 1 priority 128 path cost 20000
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?
