Open port 80 on Linksys WRT160NL?

Question

I have tried to open port 80 on my computer. Things I've tried:

• Putting the http server WAMP, online (so it servers all connections, not only the ones from own machine)
• Open port 80 in Windows's firewall.
• 80 port forward on the router.
• Put the router's management interface on https only in order to free http (port 80).

Answer 1

What you need to do is:

• Disable Upnp on the router. Upnp reserves port 80 (but the port is seen as Closed) and port forwarding will not work. Administration/Management/Upnp/Disabled

  - and then -

• Put http server online (so it serves all connections, including from outside it's own network)

• Open operating system's firewall.
• Port forward port 80 on the router.

The first one is not mentioned anywhere and it's not obvious in any way.
