Error 401: no such nick/channel:

[Lumet]

Hi, Whenever someone tries to connect to my fserve i get an error that says

Error 401: no such nick/channel: (then alot of numbers and letters)x:6060

i think it should look like (username@ alot of numbers and letters)x:6060 but it doesn't have the username. I believe i've opened all the ports i need to and i have downloaded and installed the patch for 2520. I am behind a router.

also with xdcc some people can download others can't. The people that can't, they don't get any errors and all i get is a message that says Username XDCC send #number ]

What is the best ports to set things so that most other people do not have to set mine? Thanks for all your help:)
