I am looking for some advice on configuring my new Sonicwall TZ215.
We have a network with 3 VLANs. The first two VLANs use the primary WAN as configured on the Sonicwall. I have an extra IP and was wondering about using it as a public facing (but still firewalled) address for VLAN 3. The two WAN IPs are in the same subnet, and are accessible via the same router.
Since I have a physical connection to the router on WAN (X1) can I utilize that? Do I need to use one of the other X interfaces on the Sonicwall configured as WAN? I'm trying to host a few services logically separated from our primary two networks and am unsure how to proceed.
Advice on the logic, rules, and routing would be greatly appreciated.
