We currently have SSL VPN configured for users that goes to https://website.domain.com/portal/sslvpn. However, now some of our users want to be able to use OWA/Active Sync. Since port 443 is being used by the SSL VPN, how do I change the SSL VPN to another port so that OWA will use port 443. We only have one external IP, we I was thinking we could change the port that the SSL VPN does not use 443. This way Exchange can use 443.
Any thoughts on how to do this?
You can change the port of the SSL VPN portal. On the SA 520W's web Security Appliance Configuration Utility, navigate to the Network Management Menu ->Remote Management; on the Remote management page, change the port number from 443 to 60443. This way your SSL VPN clients will come in as:
Alternatively, you can use a different port (other than 443 or 60443) but you will use a port forward from the WAN to the LAN as described on the document attached by trabb.
With the procedure on the document, you would basically be connecting to the following SSL portal:
and be forwarded to:
Both should work. Let us know if this help resolve your issues.
