Hello everyone.

I have an internal webserver running on Win2k Pro. I have set the port to
serve up on 785. I want to use IPSec filters to not only block all access to
this server (except from one box), but also to encrypt all of the
communications between the webserver and the one computer.

I was able to one or the other, but not both at the same time.

Here is a summary of what I am trying to say-
1. Block everyone except 10.0.0.15
2. Only allow 10.0.0.15 to connect to 785 and nothing else
3. Use IPSec to encrypt the traffic between the two

Both are Win2k Pro boxes.

This should be possible, right? Am I overlooking something simple? Any help
would be appreciated.

Thank you.
