List-Unsubscribe: , List-Archive: Hi: I've never forwarded speak freely, but the below worked for me when using buddy phone on a windows box behind my linux machine, so it should work just as well for speak freely. I use the ipmasqadm program to do port forwarding. This requires a few things to be compiled into the kernel, namely the port forwarding stuff. I think the ipmasqadm docs mention this. Don't confuse ipmasqadm with ipfwadm, the program that was the equivalent to ipchains in the 2.0.x kernels. I suggest a command like so: ipmasqadm portfw -a -P udp -L 2074 -R 2074 Where external IP is your regular IP address that your firewall box has, and your internal IP is the machine on the inside where you want speak freely packets to go. You will need UDP ports 2074 and 4074 to be forwarded. On the rare occasions where I've had to use speak freely behind a firewall, I found performance much better if I only forwarded these and not 2075, 4075, 2076 and 4076 as well, but your milage may vary so try that too.
