also, i tried this:
http://jdc.parodius.com/irc/dcc_nat.htmlnow, i can send to some people with normal speed, but to some people i get the same problem. startout slow, and then drop to 0 kb/s upload..
with those people were it happens, it says in netstat -na in DOS for example this:
11.11.11.11:34290 66.66.66.66:50001
where 11.11.11.11 is IP of receiver, and 66.66.66.66 is my IP. the port 50001 is correct, since i changed that in mIRC, obviously, port 34290 is NOT correct !
When i send to people with no problem, i see
11.11.11.11:1024 66.66.66.66:50001, which seems normal..
Any clues ??
and also, What router DOES NOT have these problems ???
Also, mIRC DCC send part needs to be rewritten so that it works properly with NAT !!!
