I`m using a cheap 4 port router right now [Network everywhere] an off brand from linksys.Originally posted here by cgkanchi
That's because your IRC client runs an IDENTD server.
When i ran the grc.com sheilds up test port 113 reported "closed" status.This results in not passing the "stealth" test. To fix that and make it "stealth. Just forward port 113 to something like 192.168.1.234. Where as that doesn`t even exist.
Then it should be stealh. I think some IRC servers require you to have IDENT enabled but i haven`t had any problems.
Maybe off topic but i thought that may help some.
