Hi,

First off all i want to say that i am not a novice user and have knowledge about networking.

I want to use the direct connect feature on limewire but having some problems.

I have 3 clients (limewire). ClientA and ClientB have real ip address and have no firewall. ClientC is behind router (USR 9106). I can successfully connect from ClientA to ClientB and ClientB to ClientA.

The problem is connecting to ClientC. Anyone can connect to ClientC but ClientC can connect to the other clients with direct connect. I setup the router and ip forwarding. Limewire says that "When your friends wants to connect to you, they should enter ......." but still noone can connect to this client.

Firewall: off (both windows and router)
Listening port: 4042 (both tcp and udp are forwarded from router)
Router configuration: Manual port forward (6346)

Any ideas?

You confuse me. Router forwarded on port 4042, but router configuration of 6346. I'd suggest both should be the same. To connect to the gnutella network, you don't have to use port 6346, that's just the official gnutella port.

I think you meant to say in your 2nd paragraph that client C cannot direct connect to the others, right?

If all is ok, then the ip should show above the direct connect search box. If it's not there, then there's a firewall problem. Does client C show the brick wall icon at the bottom of the window?

Also with direct connecting, you need to have available bandwidth & slots for both up & down.

Out of curiosity, has client C tried sending a magnet link to the others to see if they can download from it?

Also, I've heard it said that it's better to do a separate port forward for each of UDP & TCP (using same port no.#). That's how I've done mine.
