We have just installed a new Sonicwall TZ 205 firewall. We would like to setup a secure access to our systems using SSL VPN through the sonicwall. The problem is that we have an Exchange Server which is using Active Sync over port 443 to snyc our staffs email with the server. Active Sync uses port 443 to sync the devices.
In setting up the sonic wall, under interfaces we have to turn on the HTTPS option for user logins which is screwing up the sync with the devices. I am pretty sure you cant change the listening port on the IIS side for active sync. I am not sure how to setup the sonicwall to use a different port to setup the secure connection.
