Hi

If you mean terminating on a firewall you don't have to open any ports as the firewall will allow IPSEC connections.

If you mean through a firewall

UDP 500 isakmp

IP 50 ESP

IP 51 AH ( note this is generally not needed)

If you need NAT-T then udp 4500

if you need IPSEC over TCP port 10000

HTH
