ENDIAN Firewall

Hello,

I'm using Endian 2.4.1. In my Orange zone I have an asterisk server usuning by default 5060 port and 10000:30000 RTS ports. For that configuration everything works perfectly good. There are rules for SIP and RTP on the firewall set etc.

Now I have another asterisk server outside which uses port 5070 and the same rage of ports for RTP. I added firewall rule for the port. The connection can be established but there's no sound. The first thought was RTP problem and in fact it is. I checked with logs and wireshark. The problem is that for sip port 5070 it ok but for rtp there's an internal orange ip address sent to the other side. AS I said for port 5060 everything works well.

Can anyone advaice how to overcome this issue? In my opinion it's nat translating problem on firewall.
