Interesting, can you please elaborate because when I walk through the Server Publishing Rules Wizard, I put in the IP address of my internal network server: 10.128.3.1 and then try to put the IP address of my ISA's DMZ interface: 10.112.1.1 where it says "External IP address on ISA server" it get a message box stating: "The IP address specified is not external" If I click the "Brows" button next to that select it displays only the external interface IP's -Casey
