How to open Zywall USG110 for OWA access?

Hi,

I having issues with Zywall and Exchange. I want to access OWA from outside but it seems the firewall is playing funny games with me.

- When I access my public IP with https I hit the firewall welcome page
- When I NAT https to exchange server then it says "The connection has timed out"

I've done the following:
- Configuration - Security Policy - Policy Control - rule for service HTTPS to  server.
- Configuration - Network - NAT - mapping for service HTTPS from WAN to Exchange server

Please help me out.

I haven't seen one of those for a while, but I am pretty sure it has an SSL VPN feature. That will be listening on port 443. You need to change the port it is listening on so that the HTTPS traffic goes through.

Thanks Simon, i'm looking into it. So far there is no option to switch SSL VPN off or port configuration. Also I see they have a new firmware, I'll download, upgrade and post updates.

The issue was the device reserving port 443 for itself, changing the device https port to 447 solved the problem but it took some time to work and I dont know why it happened that way.
