Upgrading to the latest firmware of: 3.6.4_sb_232201 breaks SSL Port forward.

I am not sure whether this is a new feature or it just switches it on.

After upgrading to the latest Firmware my remote email and all remote SSL features of my Server stopped working.

The Certificate was showing as invalid. Upon diagnosing further I found the external IP was stopping at the Router.

After digging deeper I noticed a section named SSL VPN. This is using port 443 and hence the reason the port forward gets stopped.

Drill down to:
SSL VPN > General Setup > SSL VPN General Setup and change this port.

Upon doing that the Remote services are now working fine once again.

This is very annoying and has wasted time trying to diagnose this issue.

When upgrading firmware nothing should change from a working system. I have been very happy with Draytek products but this kind of sloppiness isn't very good to say the least.

I hope this saves someone countless hours of pointless diagnostics.

I had the EXACT same issue. Even with that SSL VPN service inactive, the router still seems to run/block port 443 incoming. I had to activate the VPN service, change the port to something else then deactivate before my 443 forward rule worked.

VERY annoying!

Sure but the fact even when SSL VPN inactive/ unticked, it still blocks incoming 443... this must be a design flaw.
