2.If EP1 and EP2 is register success in GK and GK setup is route mode
If i is EP1.When i make a call to EP2.
EP1 send a Q.931-SETUP to GK through NAT1,then GK routed the Q.931-SETUP
to NAT2.But NAT2 drop the Q.931-SETUP message.Because NAT2 have not
EP2's static address mapping.If i setup the NAT2 static mapping EP2
the call will work well.

setup NAT2 static mapping will solve question 2
but most voip user can not do NAT2 static mapping
and static mapping only server one voip user behind NAT
i do not know that gnugk have any solve solution about question 2.(public address to NAT)
If have any more good solution for question 2.Pleae tell me ..thanks
