I am trying to get OpenVPN in bridge mode (TAP) to work, as I would like to use VoIP phones without any further configuaration as I would use them inside the LAN . I have two WAN ports with working TUN VPN servers running, so I assumed TAP wont be much different.
When I do use the OpenVPN client and connect to the local address of the bridge it works fine and gets an IP address from my DHCP.
However if I use the WAN address from outside it gets stuck at the UDPv4 link remote and nothing happens.
I applied a firewall rule from my WAN2 connection to allow the port (4913) as I did with the other two TUN servers.
I kind of followed this guide:
