Thank you for the comprehensive information Phil!

So, if I wanted to configure Viktor ip rules for IPSEC, which he
previously provided in this thread,

iptables -I INPUT  --match policy --pol ipsec --dir in --proto esp  -s -j ACCEPT
iptables -I OUTPUT --match policy --pol ipsec --dir out --proto esp
-d -j ACCEPT

how would I do it in firehol?

Do i have to add a custom rule? I'm still unsure how to do this and I
wanted to keep my firehol.conf as clean as possible.

My best regards,
