NAT Loopback with Firewall Enabled was created by lightpathit
I have a DrayTek 2930Vn running 3.3.1.1 and am struggling to get a NAT Loopback working with a firewall enabled and the external port being redirected to a different internal port.

I have been hosting a website on my internet connection using port 443 on the public site, but it was redirected to port 6000 on the LAN side. When I used to connect using a domain name that resolved to my external IP address everything worked perfectly due to NAT loopback being enabled.

Today I have enabled the firewall as I needed to restrict access to some services via IP address and this feature no longer works. It is working externally, but not internally. I have added a filter rule that allows all 443 incoming traffic as well as one that allows all 6000 traffic. There is no restriction by IP address. When I use a service on the same domain name that uses the same internal and external port, everything works fine.

Any help on this issue would be much appreciated.

Thanks in advance.
