Re: NAT and H323

["Paul Haesler" <paul@phaesler.org>]

I tried portfw, autofw and a couple of 2.2 kernel helper modules 
(ip_masq_h232 and ip_masq_netmeeting) and various combinations
of the above.

I was able to get bits working.  Some bits would only work one 
way, some bits wouldn't work at all.  Some bits worked fine.  There
seemed to be a lot of black magic involved and I didn't have the time
or facilities to investigate it properly.

I gave up - but that doesn't mean you should.  If you search the 
web you can find people claiming to have the magical incantations 
to get Netmeeting through NAT.  The incantations change with 
every new version out of Redmond, but if your organisation can 
standardise on the one version you should be able to get it 
working with enough persistence.
