I have successfully set up a NAT proxy through a machine with two NICs via the RRAS NAT special ports
x.x.x.4:80 ---> 10.0.0.1:80
The 10.0.0.1 machine is a Sun box. This works fine.
However, doing exactly the same thing to an IIS webserver (on another Win2K machine 10.0.0.2) doesn't work.
x.x.x.5:80 ---> 10.0.0.2:80
x.x.x.4:81 ---> 10.0.0.2:80
x.x.x.5:81 ---> 10.0.0.1:80
It seems it works with the Sun webserver but not with IIS!
The 10.0.0.2 machine can serve pages quite happily to the
other machines in the 10.0.0 network.
I have also tried two other Win2K IIS webservers, also on the internal network, and I can't get them to respond through the NAT proxy either.
* Under Default Web Site properties of the target IIS webservers: IP Addresses are "(All unassigned)", there are no Host Header Names and pages served on TCP port 80.
* The NAT server has multiple IPs on each of its NICs.
* There is an IIS webserver on the NAT server (answering to a different IP), but I did try switching that off as part of the tests.
I am totally stumped.
Can you help?
