I am trying to publish an FTP server using the Server Publishing wizard. I am at the tab labelled Address Mapping and am trying to set the External IP address of the ISA server. When I select Browse there is nothing returned to the address list and if I specify the address directly it responds with the following error; The IP address specified is not external.. The address is an external public ip address, which I have added to the external network card... I don't understand why there are no addresses in the list.. I suspect that I am missing something out, but I have published web sites, terminal servers and setup a VPN without any problems. I haven't come across any issues like this before and the resources available on the web have not provided any clues.... If anybody has any suggestions, I would be greatfull... Cheers
