Losing Internet on GoldenOrb with Wireguard VPN Active

[slazinger_7]

I am able to activate and run Wireguard VPN on GoldenOrb 2021-05-18, but the internet eventually drops.

The internet connection is through ATT and my understanding is that we are behind a double NAT and thus need to change some firewall settings to get the system working again.

We tried the following code under "Custom Rules", but it didn't work:

PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

Does anyone have suggestions?
