Hi, i just looked at this again. I turned on ekiga in one computer, then
turned it on in the other. ON the first computer, everything worked, I
could see that my user on the machine was on, i could see that the user
on the other machine was also online. Echo test also worked, (i got
"remote video").

However, on the second computer, echo test still worked like it did on
the first machine, but presence didn't seem to work at all. I didn't get
grey for people offline and green for people online, i just got the
little people things, if you understand my description. The user I had
on that machine (machine 2), was online according to machine 1, but not
according to machine 2, since I had the user i was using on machine 2,
in my contact list on machine 2.

I'm assuming that if presence works and echo test works, the machine is
functioning in such a way where it can make and receive calls.

IN response to the other response, the Avahi implementation of Lan
calling works perfectly to contact both computers, and it always has.

I should also describe my network connection a little more. I have a
modem and a router that both have NAT, so I'm double NATed. Right now,
to get Ekiga to work on any computer I have to forward port 5060 UDP on
the modem (only the modem), and Ekiga will work (with the problems I"m
describing in these posts of course). However, Ekiga always has
displayed the notification on startup where it says it cannot detect the
network settings although it is working, once again, with the problems I
am describing above and in these posts.

I don't like putting the router into Access point mode and I don't have
the password that I would need to put the modem into bridge mode. I can
forward the ports in the router and the modem, but my router seems to
have a quirk, where if I forward anything in the router, I can't connect
to IRC, gmail, gtalk, or things like that from any computer. (I know,
that's weird, and has nothing to do with what we are talking about in
this topic.)

Hopefully, I've done a better job of describing the situation over here.
Thanks for listening and helping!
