NetMeeting Through a NAT Router?

Apologies if this is a FAQ, I have down-loaded and read the last 300
messages in the group (back to April) and have seen odd references but
nothing definitive.

I am running NM 3.01 on XP Home SP2, connected to the Internet through
a Draytek Vigor 2600G.

I have re-directed ports 1503, 1720 and 1731 (TCP) to the local PC and
opened all ports from 1024 to 65535 (UDP), which worries me a bit.

Windows firewall is disabled but I am running Kerio Personal Firewall,
NM is 'authorised' by Kerio.

I can receive incoming incoming calls and sound, sharing etc. all work.

When I make an outgoing call the person at the other end can hear me
but I can't hear him. He also has Kerio running and it shows my call as
originating from 192.168.1.14, not very helpful to his copy of NM :-(

If I put my PC in the DMZ on the Draytek everything works fine, but I
would rather just open the ports that are needed rather than opening
everything up.

I have Googled and read several articles, they range from easy peasy
just open a few ports to it's impossible don't try.

I have also asked Drayek (no response so far) why the router is sending
out an internal IP address, I don't know enough (anything) about NAT to
even know if this was a sensible question.

Any suggestions or pointers to guides would be very much appreciated,
we use NM for support amongst a small group of us so getting it working
with calls in both directions would be really useful!

Many thanks.
