I have need to change the internal IP addressing structure of my network. All went well, with one exception. My Exchange server (2003 sp1) is working fine, emails flowing no problem at all, and internally OWA is working OK - no problems at all. The problem I do have is that external access (simply using http://internet.facing.ip.address/exchange
) is now not working. The browser just sits for an age and fails to load the page. The server's public face is not behind any type of a firewall - I know it needs to be, and it will, I'm just trying to make the darned thing work.
Any advice would be deeply appreciated.
