Howdy y'all,

I was wondering if anyone had any advice for me.  I hooked up a video camera
and a microphone to my wife's Windows 2000 computer and installed Microsoft
Netmeeting on it for her.

It looks like Netmeeting and other H.323 stuff should work through the Linux
kernel IP masquerading.  I'm using a Linux system as the gateway to my
static-IP-address DSL connection at home.

I read some HOWTOs and other documents, I downloaded the ip_masq_h323 module
as well as the ip_masq_netmeeting module, compiled & loaded them into the
kernel, and still Netmeeting won't register itself with the directory servers
that provide connectivity (I think) between Netmeeting sessions.  It looks
like Netmeeting tries to open a couple of sockets to the directory server on
port 1006 or 1001 or something like that, but the sockets always stay in a
state of SYN_SENT (according to netstat on W2K) and never go to ESTABLISHED
state.

Here is some information about my kernel & system:

The ip_masq_h323 and ip_masq_netmeeting always stay in a state of "unused"
(with used-by 0) even when netmeeting has its sockets in a state of SYN_SENT.
Masquerading for all the other protocols I've tried, including FTP etc., all
works fine.  The h323 and netmeeting modules compiled & installed with no
errors.

I am not trying to "receive" Netmeeting calls at home - just place outgoing
calls.  I think the directory servers etc. handle connecting the two parti-
cipating computers together anyway.  As you can see from the ipchains output
I haven't set up the incoming port forwarding to her computer.  Do I need to
do this?

If anyone has any suggestions for me I'd love to hear them.  Thanks!
