I searched and searched, so I'm starting to wonder if I'm just using poor criteria or describing my issue poorly. I've narrowed it down to something having to do with NAT or routes...
So here's the scoop.
We have two networks on our LAN that are trusted. For purposes of this question, We'll call them X0 and X2. X0 PRIMARY LAN and X2 OFFICE LAN.
We have servers sitting behind the router for WEB, FTP, etc. Users from X0 can access our public sites just fine without any issues that are behind this router. The sites are all behind the router/firewall with public IP's but have one-to-one NAT in use that forward to a local address on the X0 interface from the public side.
Now... when users from the X2 interface try to access public sites that have servers on the X0 interface, they cannot.
Sounds like either a route issue or a NAT policy. This is a Sonicwall product, but either way, this issue may be too specific for a general answer?
