Is reverse Proxy required for external web

[Jean Philippe Breton]

Running Skype Business 2019.

Using a Fortigate firwall.

Edge is working but reading in many place that RP is require to access Web Services (meet, dial, lyncdiscover) from external users.

Can I just forward traffic from 443 to 4443 on my fortigate?

Hi John, yes it is recommended that a reverse proxy is used and for external web services, this is the supported route. Whilst performing port forwarding on the firewall can achieve the desired result this does also cause a security concern, reverse proxy's are often deployed in a DMZ between the internet and the front end server itself. If your Fortigate does not have built in reverse proxy functionality, you can use the Web Application Proxy which is a part of Windows Server.
