[shetu]

I have pbx server behind pfsense and has no public ip. So I attach third party openvpn client and connect a remote extension. I froward all necessary port to pbx server. I hear other end voice but they do not listen me. From calling Lan side both way audio work.

Pfsense : 2.3.5-RELEASE

See my response to your other post --

What subnets are you using on each ?

Did you set the Local Subnets in the PBX server ?

Hi. I see your post. My port forward in pfsense is working. I can access pbx in flash web gui from remote extension. But voice always oneway audio. I use Zoiper free version. I think may be problem on pfsense NAT settings.
My local subnet in pbx
192.168.10.0/255.255.255.0
10.8.0.0/255.255.255.0
