Hello all,
I'm trying to build a jail on FreeBSD 10.1 using ezjail in order to run
OpenVPN. I'm not using vimage and don't particularly want to but I'm having an
issue with networking.
OpenVPN daemon is up and running and I can connect successfully as a client. I
receive an IP address as expected, but I cannot route traffic to/from
client/server. The routing table on the client (which is a Windows machine)
looks fine so I assume the issue is on the server side. I have a tun interface
created on the host and exposed to the jail via devfs rules. The IP address on
the tun interface is configure on the host and not from the jail. I can ping
the tun interface IP from the host and the jail, but not from the client when
connected.

I'm a little stumped as to how to trouble shoot the issue so any help much
appreciated.
