There is one setting in X-lite (under "Network") that can cause
one-way audio. It used to be called "Transmit silence" and should be
on. It is now called "Preserve bandwidth during silence" and should be
UNchecked. If this is a small installation you don't need 10,000 RTP
ports, they could be something like 10000-10020. This matters if the
router doesn't allow a range in the forward parameters.

As a last resort, go to the Free World Dialup forums and look for one
way audio or firewall or nat and xlite. There are a large number of
solutions there.
