we have an Sonicwall NSA 3500. We have two dedicated lines going into it; one is a 4/4 and the other is a 10/10. The 10/10 has been set as the 'primary' WAN ethernet interface. The issue I'm having is that the 10/10 seems to accept VPN's, however whatever I do, I can't get anything connected on VPN to the 4/4.
Any ideas why or how to diagnose this?
