I have a FreePBX System 60 I am having a little trouble with one interface over a vpn connection.
eth0 connected directly to telco’s SBC - 172.16.1.2 /24
eth1 VOIP Network 10.0.101.4 /24
eth2 Office LAN / Internet connection for updates 172.17.194.20 /24
When I try to connect to the 10.0.101.4 interface over the VPN (OpenVPN on a PfSense gateway) the FreePBX box does not reply to ping/sip/web requests. A tcpdump on that interface shows the request but no reply. I checked the other interfaces and the reply is not going out those either. However, if I use the eth2 address everything works as it should. It is just not the network I would like that phone connected to.
I have added all of the associated networks to the firewall as local trusted traffic. I have also added all of the associated networks to the local network list in the sip nat settings.
Thanks!
