Which ports do you need to open on a firewall to allow To enable VPN tunnels between individual host computers or entire networks that have a firewall between them, you must open the following ports: PPTP. To allow PPTP tunnel maintenance traffic, open TCP 1723. To allow PPTP tunneled data to pass through router, open Protocol ID 47. L2TP over IPSec. To allow Internet Key Exchange (IKE), open UDP 500.

Ipsec needs UDP port 500 + ip protocol 50 and 51 - but you can use NAt-T instead, which needs UDP port 4500. On the other hand L2TP uses udp port 1701. If you trying to pass ipsec traffic through a "regular" Wi-Fi router and there is no such option as IPSec pass-through, I recommend opening port 500 and 4500. At least that is how it works on mine.
