Hi, I'd like to have a web server running internally on port 80 and I've mostly got it working with one issue.
The lan is configured 192.168.2.0/24 and there is also an ip routed lan configured to 46.37.x.x/29. The firewall is configured to block everything unless permitted.

I've setup the open-ports in the nat settings (is there any difference to this and port-redirection? Does the latter need firewall rules as well?)
I've disable external http management calls and changed the port to 81 for http.
I've setup rules in the firewall to let port 80 in.

Given that, all seems to be working ok externally, but there are issues internally. Using a LAN address (192.168.2.x) sometimes I can connect to the server whereas other times it just times out. Is there anything I should check?

Secondly, I have some servers which are on external ips (eg 46.37.x.y) and these cannot connect to the http service using the address of the router. Do I need to add any additional routing or firewall rules to enable this?

Thanks
