What are the differences between the LAN and WAN ports?
It seems like a simple question, but what are the functional differences between the two types of ports? What functions, generally, apply to the different ports? Why is there a distinction between WAN and LAN?
This is in the context of a Site-to-Site IPSec VPN. Can I define a VPN with one of the WAN interfaces as the "local" interface? I have such a VPN defined, but no packets are passing. The VPN is up, and I have static routing set, but no packets are passing.
