Draytek 2860 Port 443 / SSL not working port forward

draytekThere seems to be a bug in the Draytek 2860 router, even though I had changed the management ports from the default 80 and 443 to 8080 and 8080. I was still unable to port forward any 443 traffic and would end up getting an 404 error page from the Draytek 2860.

The next thing I tried was to disable the SSL vpn in the remote/vpn section, this made a change as I now no longer got the 404 error page from the router while trying to browse to https://mail.mydomain.com but still the port forwarding was not working.

After drilling down deeper into the Draytek 2860 SSL VPN settings, I changed the port the SSL VPN uses from 443 to 44444. I did not think that this change would make a difference as the SSL VPN was disabled, I was wrong!  The 443 port forward started working, so even though the SSL VPN was disabled, it seems that port 443 was still in use by it.

I hope this post helps others!
