We have several branch offices that I have set up with OVPN in Peer to Peer mode. That has worked great for quite a while. I set up another OVPN connection from our main office to one of the branches to connect some phone extensions back to our asterisk server at our main office. I put it on a separate VPN tunnel to be able to do some traffic shaping. The extensions are a vlan (v110) at the branch office and the asterisk server is also on v110 at the main office. I know the VLAN tags don’t persist across the tunnel, we just standardized all of the voice traffic at all locations on v110.
For the life of me, I can’t figure out why I can’t access my asterisk server from v110 at the branch office. I’m assuming I am missing something at the firewall level. Does anyone have any ideas?
