which are the ports needed to be opened for ipsec vpn to pass through?

we using a network like this

lan ---> pix (doing pat) -----> internet(dsl) ----> vpn server

about 20-30 clients on the lan need to do vpn to server.

we r using safenet ipsec vpn client

pix is 506e

what ports needed to be opened to allow vpn? is it protocol 50,51 &udp

500

you need to pass source and destination UDP ports 500 and 4500, unless you don't use TCP for IPSec...UDP is default. Also, esp and ah traffic must be passed trough.
