I recently setup a 506E, behind an Efficient Systems 5851 SDSL router. The router is set to use public addresses (no natting). I am port forwarding 25 and 80 from the public interface to an internal mail server. Is there a way to use another public IP (I have 4 free) rather than the interface IP? I used the wizzard to setup the VPN, which I've used before successfully, but I'm getting a no response from the 506 when attempting to connect from the client. Using group permissions. The same laptop/client successfully connects to another 506E which is in production so I know it's not the client or laptop. Could the router be preventing IPSec/UDP from passing through? Any concise way to confirm this, if so? Monday I'll blow off the VPN setup and run the wizzard again but this process is usually pretty simple and has worked in the past for me.
