We have two sites, site A has a fibre connection to the internet that is presented as an ethernet port. Site B has a connection to site A that runs over our provider's fibre network.
So at Site A we have two ethernet sockets, one that gets access to the internet and another that gets us access to Site B.
We've purchased a sonicwall TZ210 at each site. At site A we have a TZ210 with the internet fibre connection plugged into the wan port, and Site B is plugged into one of the lan ports on the TZ210 at site A.
Down at Site B, their connection to Site A is plugged into the WAN port.
Everything works fine, but when Site B accesses network resources at Site A, their traffic is getting NAT'd.. which would make sense seeing that is how the sonicwall would be default set up.
So how do we disable the NAT on the sonicwall at Site B so that their internal traffic is not NAT'd?
