i'm setting up a rv082 using a single wan and can't for the life of me seem to get it to forward sip & rtp packets to an asterisk (voip) server. I'm getting one-way audio (I can't hear the remote party, but they can hear me) which is a classic symptom of inbound packets not being forwarded. I have tried adding and enabling the correct ports to the port range services list, added firewall access rules, disabled the firewall, and even DMZ'ed the asterisk server- with no success so far. We received it with 1.3.2 firmware and have upgraded it to the latest beta (188.8.131.52), neither of which i could get working. The port ranges required for SIP VoIP are huge, the rtp range is from 10000~20000 UDP. But lessor routers have worked great for us with this setup including most of the WRT54G line. I'm stumped!
