Hi to all!
I'm using the 3CX PBX since 2 years behind a ISP router, and it works perfectly,
Now I added a load balance router behind the ISP router in my office network and opened all the ports needed by 3CX on the router.
The problem is now that I can't hear the incoming voice from the phones!!
This is the log of the firewall checker, as you can see there is a warning on the port translation.
How can I disable the port trasnlation? I can't see no option in the routers!!
I also found this problem in the 3cx log:
Actually the router are set in this way:
DSL router 1 (main DSL line, Static IP)-> all the ports opened to the Load balance router
DSL router 2 (backup DSL line, dynamic IP)-> all the ports opened to the Load balance router
Load balance router -> 3CX server (Win 2K8 enterprise) opened ports: 5060,5061,5090,5000 and the range between 9000 and 9050.
I also set on the load balance router that the whole traffic generated by these ports should pass through DSL router 1, that has a static IP.
How can I resolve this?
