Re: 求助! 關_語音聊天 behind NAT

[Alex Lau <alex@dentonlive.com>]

Special socket program like anything started with "Microsoft" may need a
module e.g H323
for the kernel in order to to work. I'm not sure why H.323 module didn't
work (need debug)
but 2.4 iptable look a lot cleaner and less security issue (2.2-20 is
the current
stable kernel for ip masq ) I don't use microsoft product dont' know
what to suggest you
to use. But port forwarding should be the same as your masquerading
script instead of
just putting ip you put ip:port number

Good Luck
