Re: 求助! 关_语音聊天 behind NAT
Thanks for you immediate reply.
If I wanna write my own ip_masq module(in 2.2.x) for an voice chat
application, which is however an proprietary software, where should I
start from? or any references/links to read?
Furthermore, how to I discover the port numbers the application is using?
