Folding Forum

Hi,

There is a public webserver in my network, a typical dst-nat port forwarding rule is enabled on the router on destination port 80 and server port 80, so that people from outside the network can connect to the webserver. When this rule is enabled, none of my folding units in the local network is able to get new work assignments (please see error message from the logs below). When I turn off the port forwarding rule on my router, each local network unit is able to get work assignments again. Can anyone shed some light on that? Why is FAH failing to get WAs if there is a webserver in the network and port forwarding enabled?

Turn on the port forwarding, and use the browser to access the web page "http://assign1.foldingathome.org:80/" to see if it can be accessed normally.

The F@h client uses ports 80 and 8080 to make connections with the servers for downloads and uploads. With port forwarding on for port 80, those connections can not be made as they are being directed to the web server. There may be a way to setup your network and its router to have this still work, but I am not enough of a networking expert to give guidance on how to do it.

This is weird ... can post a little schematic of your network ? I don't understand why a request to an external server would be redirected to our internal server ...

Basically, client trying to connect to the AS and WS is the same as a browser trying to connect to a website ...

Port forwarding should not be affecting the traffic coming from your internal network, only the unsolicited traffic coming into your network.
Which makes me think that:-
1). your port forwarding rule is misconfigured, possibly attached to the wrong interface
2). it may be covering for a misconfigured DNS server, this is what should be redirecting your internal traffic to your web server

If you disable the port forward rule, can you still browse to your website using its name?
