That may or may not work depending on type of NAT you are using. See
Applicability Statement in STUN RFC3489.
Generally, more than one STUN device behind a single NAT increases
likelihood of failure. The devices may compete for the same port number
which makes some NATs change their behaviour in terms of STUN taxonomy
from asymmetric to symmetric (thanks to Andrei for having debugged this
tricky case). Then nothing will work, since the phones rely on
asymmetric behaviour which does not hold. Some NATs also discard packets
from local interface to its public IP address which breaks calls between
two devices behind the same NATs.

Hello Martin,
Please advise if you have tested with more than 2 Grandstream devices in the
SAME Nat ?

Has anyone been able to get the Grandstream HT486
to work with MyStun or
any
other opensource stun server ?
No Problem here.
I use the HT486 with stun 0.91 (Feb 21 - the latest release) from
vovida.org
Source is at
http://sourceforge.net/projects/stun/
