My ISA server have one NIC and a USB DSL Modem, wich work as a regular modem but with the advantage of DSL, I am using TZO Service to update my Domain Name with the Dynamic IP I receive from my ISP. My clients can browse the Internet with no problem, I secured my Exchange 2000 Server and works great too. The only problem I have is when publishing Web Sites. My web server is on the same ISA server, I changed the port to use other than 80 or 8080 and to point to my internal NIC as instructed by MS KnowledgeBase. The publishing works fine until I disconnect from DSL or my IP change. Then I have to do the publishing all over again to make it work. Is there any way to configure the Web Publishing so I dont have to do it every time I got disconnected from DSL or my IP Change? Thanks
