      I am currently trying to work out an IPSec VPN tunnel between a pfSense box and a pix 501.  From what I can tell the tunnel is up but I am not able to ping from LAN to LAN.

      Here is the topology:

      Here is the PIX config:

       PIX Version 6.3(5)
      interface ethernet0 auto

        Did you add the rules in the firewall tab on the IPSEC interface ?
