Hi Amos, This could be the problem. I built another VM based on Debian and ended up creating my own CA / PKI. Self-signed certificates worked and I was able to move on at last. Great learning experience to see how SSL / openssl works. Now I am stuck with Windows client unable to connect to reverse-proxyfied Exchange. When I connect via NAT/PAT, I can get to OWA/ECP. When squid is acting as reverse-proxy, connection is timing out. Looks like my Exchange SSL is not working but I will deal with this later. Thanks a lot for your help.
