powermac G4 Firewall and VPN Server

[powermi]

Hi mates, I just setup a Raspberry Pi 2 in my home working as a OpenVPN server wirh PiHole as antiAds.
Well, as a powerPc user since long time Im thinking of setting up a G4 woth the same propouse, taking into consideration adding a second Ethernet card for working as a Firewall too. But have doubs about what sofware and configuration tu use. Anyone gone trhought a similar process?
Cheers

I am doing something similar for clients with OpenBSD. This should work on a PowerPC Mac as long as it has 2 usable ethernet ports.

Traffic flow outbound from client device or network looks something like this (not exactly though; excuse the terrible ASCII diagram). The stuff within the brackets is running on the OpenBSD server:

Client--->[IKEv2 server--->Adsuck DNS--->Suricata IDS--->pf firewall]--->internet

The exact config will obviously vary depending on your needs. I could help you set it up if you like.
