I have two servers that are experiencing a strange problem. Both are OES 2
sp3 server. Fairly up to date. Both work fine on our network, but when
attempting to access from outside our network, the https connections fail.
The first instance is our GroupWise web access. The second is our
NetStorage / iFolder server. I have a support request open with our
firewall manufacturer, but I want to cover all my bases. We know of no
configuration changes between the time it worked and when it stopped.

What would cause GroupWise web access to succeed within our network and fail
from outside?
