It?s the Packet size for the media, Maximum Transmission Unit (don?t quote 
me).  There is a technical page at Microsoft called black hole routers

Have you checked the MTU size of your external network card, I had a similar 
problem, I created an entry in the registry to default the MTU size to 1400 and 
I could then browse web pages.

Question: one of my sysop guys ask if it matters that the sub net mask on the 
out side is 255.255.255.224 and the internal is 255.255.255.0 (which is correct 
for there respected sub nets)? -----Original Message-----

Do you a Packet filter for HTTP? 
Have you tried to create a rule to leave your packet filter wide open at least 
to test this?

I'm assuming that Internet people are resolving the name to the new IP address. 
Now, are the Destination Sets OK? 

What error do you get? 
I mean does IIS retrieves any page or error?
