I have 2 asterisk servers, 1 in a foreign country.
I think that my ISP in the foreign country has configured their network in a way such that incoming traffic comes through one interface, while outgoing goes through another? I am not certain if this is the case but I think that they want to conserver bandwidth usage for one of their links, thus using it only for downloading, while uploading goes through another.
On my home asterisk server, running on Fedora Core 6, I have opened up the remote IP so that the 2 servers can talk to each other using IAX2 on port 4569.
However, when I do a tcpdump I see packets going to my remote asterisk server, but the return packets appear to be from a different IP address. Can I somehow configure Asterisk to handle this?
