okay, MY ISP provides up to three dynamic IP's. This is what I am trying to do:

Cable Modem
|
Network Switch (the 2 WAN connections come from here)
| |
Untangle
|
Internal Network Switch
|
Internal Servers and Workstations

What I am trying to do is have two separate external IP's, but I have to use two separate interfaces since they are dynamic. Is this a limitation of the Lite version? I set the DMZ interface to "IS WAN" and setup firewall and port forward rules, but cannot access anything on the IP of the DMZ interface. My main reason for this is to have to SSL sites both running on 443.
