Hey everyone,

I just have a quick question .. is it possible if I have all of my network equipment on VLAN1 and all of my web servers on VLAN2, that I can NAT addresses directly from my firewalls on VLAN1 to servers on VLAN2? I have a layer 3 router doing the vlan routing in between, so the servers can talk to each other... Sorry, I don't have the equipment up and running yet or I'd just try it... Thanks in advance!

Yes, that should be not issue. As long as the two vlans can talk to one another, the NAT will work.

Have a firewall/gateway which has public addresses.. I plan to map those public addresses via NAT to another VLAN on the network... so the firewall would be and the web server would be the Web server would then point to the default gateway of or (the L3 switch IP)? I'd then NAT a public address of to that web server via the firewall..

Oh okay, I don't see why that wouldn't work.
