[Kanishka Somaratne]

Hi
I have asterisk running on a server out side the office, this is with real 
ip. i have 1 realip to office and we share internet through nat. i have 5 
SIP clients registered to asterisk from behind nat.
when one of the sip cleints dial another sip clients extention the call does 
not come. when some one who is out side the nat calls, the call comes.
I also have nat = yes under SIPcleints.

what did i do wrong. please help me.
