Unless Im mistaken (entirely possible), an IP enabled phone has 2 distinct and separate "stacks", the IP stack and the "phone" stack. As I said, in a NAT'd scenario the IP stack will never see an unsolicited request and hence not respond to it. The phone side of course will ring when called. Duh. GPRS <> VoIP (yet) Jm

A NAT'dcell phone wont, cant ever, respond to an unsolicited connection request.*RING*!! *RING*!! Oh, I'm sorry, that was the clue phone ringing - it couldn't be your phone, since it wouldn't answer an unsolicited connection request.... You were saying? (To fill in the blanks - get a trojan loaded into the cellphone/PDA combo, and then send it a page telling it who/what to attack). -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
