SSL VPN Using Sonicwall TZ205 - Port 443 Conflict

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.

You can change the SSL VPN port by going to "SSL VPN" section (from the menu on the left), then select "Server Settings". On that page there should be value box to change the "SSL VPN Port". In this situation, you could change it to 4443 for example.

So for staff accessing it via a web browser, they can just go to "https://your.domain.com:4443". If they're using SonicWALL's Mobile Connect app on their phone/tablet, just enter the hostname/IP and it should automatically pick up the non-standard port.

By default, SSL-VPN should be setup on port 4433 regardless: https://www.fuzeqna.com/sonicwallkb/ext/kbdetail.aspx?kbid=6461. SonicWALL sets port 4433 for this reason to avoid conflicts like you are experiencing.

I'm glad I could help. Thanks for the points.

P.S. Comment http:#a39459397 should not be included as the answer as the port specified is incorrect. Port 4443 is not the default VPN-SSL port used by SonicWALL.
