I have two RV042's connected by VPN tunnel supporting two Nortel BCM telephone systems. Everything works great until we set up port forwarding for some external services. As soon as a port is forwarded we loose audio through the tunnel even though the VPN is still set-up and working. This is version 126.96.36.199. I saw a thread that said that 188.8.131.52 was a better version but before we go there, i am wondering if anyone has any ideas as to how to fix this problem. The ports that we are forwarding are 3389, 80, and 443. I suspected ports 80 and 443 so we just set up port 3389 but the problem exists with only 3389 forwarded. Linksys support was very helpful - we don't support voice over VPN on our routers. Gee thanks for the effort!!
