We can see that as a limitation of the GUI. In the next release, I'll
make this alternative methods, as they are really not usable at the same
time.

I think it doesn't give a problem to have both activated though.

I don't understand the question. Do you mean, how can it be reachable?
You still need to forward 1720, or it won't work.

Perhaps it really is, entries in ILS are not necessarily removed
instantly when the person exits the program (some people do not exit at
all, or register to ILS without port forwarding).

Actually, if your type of NAT is symmetric :
- you need to forward all ports
If your type of NAT is not symmetric :
- you only need to forward port 1720 to be reachable

If you want to use Netmeeting :
- you need to forward the TCP port range, in all cases.
