OpenRC iptables load/save [slvd]

Hey, God bless you all!

I installed Gentoo this weekend on my Raspberry Pi 4b and it works amazingly fast! Hallelujah!

I didn't went with systemd because I want to learn OpenRC and don't bloat my system too much, even though I also like systemd service files and how easy it is, but since I don't know OpenRC it's probably pretty easy too, I just have to get comfortable.

So after installing a couple of things I installed PiHole and Wireguard-UI in a docker and I loaded up the Wireguard module, I could connect to the network and to the PiHole, but I couldn't access the internet and after searching for a while on internet it were 2 iptables lines that I needed:

iptables -A FORWARD -i wg0 -o eth0 -j ACCEPT
iptables -A FORWARD -i eth0 -o wg0 -m state --state ESTABLISHED,RELATED -j ACCEPT

Internet working! Great!

Then I `rc-service iptables start` and `rc-update add iptables default`

I've searched the internet and read the Gentoo handbook but it wasn't very extended on OpenRC. I read the /etc/init.d/iptables script but I am not sure if it saves and loads the rules when it's started and stopped. Can someone explain a bit please?

Nevermind I think it does!

I'm reading it again and it does checkconfig and then saves it if it's not there, and on start it does a restore!

I didn't even read it properly! :oops:

Sry for the spam.
