[Freeswitch-users] Can uPNP be turned off?

The router (Linksys RV042) has a problem that caused me grief with FS: I
use dual wan, 1 static and 1 dynamic DSL. It turned out uPNP only works
for the dynamic ip. If I turn off dynamic then uPNP does not allow FS to
get the nat info for the static line. But if I have both wans active/on
and sip traffic goes out the static uPNP reports the dynamic as the
public address! This messes up the ITSP and looks like what caused FS to
stop incoming calls after several hours.

What drove me nut is: I did not think this was involved because my
Linksys SPA9000/400 SIP PBX has no trouble with the same dual wan setup.
Thanks a lot for answering but until I figure out how to dual wan FS or
replace the RV042 with something better the autonat: looks like
it fixed the problem, need more hours to test. Thanks again. Mario
