I have seen a couple of threads on this forum regarding the lack of support for VoIP in the WRT54GX4 unless you turn of the firewall. I have the same situation using Sunrocket. Unless I turn off the firewall in my WRT54GX4 the call quality is terrible. Has anyone found a solution besides disabling the firewall? I found a note from someone claiming that it would work if you assigned the adapter a static ip and enabled port forwarding, but it did not ellaborate. Anyone got it working this way? Thanks.
