Great, thats what i wanted to know! I was trying to access CGP using https://mailserver:9100/exchweb which didn’t work, obviously.

I’ll try this as soon as possible, thanks!

To add SSL Support I only have to generate certificates and add them to the config file? I’m quiet familiar with apache, so you don’t have to go into details…

Yes there is, with Apache it is fairly easy using "mod_proxy", I wrote a response to this list a while back detailing the basics, so I will just lazily refer to it, if you have any problems then I might be able to help (using SSL certificates adds a small bit of complication, but I cant remember anything extra I had to do off the top of my head):

I initially had the problem that we only have one public IP address and already had a webserver setup on HTTP 80 and HTTPS 443.

We run Apache on our webserver, and after a bit of research, I found that I could add redirection just for the AirSync URLs to our mailserver. All I needed to do was recompile Apache with the "mod_proxy" module and add the following two lines to the http config:

ProxyPass /Microsoft-Server-ActiveSync https://mailserver:9100/Microsoft-Server-ActiveSync
ProxyPassReverse /Microsoft-Server-ActiveSync https://mailserver:9100/Microsoft-Server-ActiveSync

(Note: we run our mailserver HTTPS on port 9100)

Just thought I would share in case it helps anyonw. As we now have our webserver working like usual, and AirSync enabled for our windows mobiles.

Hello List,


Is there a possibility to do some reverse proxying for Airsync with CGPro, using apache or squid? My mailserver is inside a company network, and I won’t allow direct access to it.
