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.

This tutorial assumes that the WAN interface of the Mikrotik router has a public IP address, and that your ISP does not block ipsec ports. With that out of the way, lets get started. The first step is to create a PPP Profile on the mikrotik. We will use a 192.168.102.1 for the local address (the VPN Gateway), assuming this is not already in use. We also need to add a DNS Server /ppp profile
