Hi
You can open with conduits/access list for protocols 50 and 51 (ESP and AH)
to let pass the ipsec connection, plus UDP for port 500 ( I think)  for the
ISAKMP
connection if you are using IKE or similar.
BUT I would recomend you don�t let pass a ipsec tunnel through your firewall,
as it can not inspect it. The "correct" way would be to end the tunnel in the
pix,
and the process the traffic to let it pass or not.
