IPSec is just usually an abysmal inane thing to set up, with defaults from the 90s and an extra bonus of error messages and documentation that just make you cuss. I don't recommend anyone IPSec, whatever it offers, after you spend all the time making sure your configuration is good, is really not worth it if you can do Wireguard or even OpenVPN. Ugh, I'm annoyed just thinking about it again.
The best part is when you find out your phone supports set of parameters A, your tablet set of parameters B and your MacBook set of parameters C.... and there's no intersection between sets.
