Linksys router and port forwarding

Anybody here have experience with port forwarding?

Here's what I would like to accomplish...

I do a lot of transfers with friends via IRC, and have recently purchased a Linksys router. Before I had no problems at all with connections to my server. Now my friends can not access because the router is blocking the ports. This is what I think anyway. When the router is connected I also can't receive any files via transfer through any of the instant messengers.

If anybody out there could help I'd surely appreciate it!!

 

Something similar happened to me I took my firewall down and it worked. If you have one try it.

 

You first need to determine which ports you need open for these services. Then go inot your router config and ther shouls be a page for setting up server services behind the router. Go to your web browser and type in 192.168.0.1 and enter. It should prompt you for a username and password. If you never set eiter just enter admin for user and hit enter.
