  VPN server

My server is behind two routers, the outer being a Vonage VoIP RTP300, and the inner being a NETGEAR N750 (WNDR4000). I can connect my client to the RTP300 and direct the VPN to 192.168.16.103 and it gets forwarded to Mozart just fine. However, when Cray is outside and I try to direct the VPN to 76.xxx.xxx.xxx, which is supposed to be forwarded to 192.168.16.103, it hangs. 192.168.16.103 is static, and I've even tried putting it in the DMZ. Any other clues?

Thanks,

Okay, so based on what I can read, the Vonage router is really a piece of crap. Works fine for my VoIP, but the port forwarding just plain doesn't work.

Had another router I was planning to install as my outer most firewall, and installed it earlier than planned. Very cool, all up an running.
