ICMP to Hosts Routed Through Gluetun

[jiriteach]

Hi - I have successful setup Gluetun and have 3 or so devices routing through Gluetun where their default gateway and DNS is set up Gluetun.

192.168.2.x is the subnet.
Works well.

On my other subnet - 192.168.1.x which can talk to 2.x - once I add devices behind Gluetun - I can no longer ping them.

Anyone know how I would enable this? Thanks

If I set a ping going against one of the devices behund Gluetun - I get no reply. If I set firewall=off I get a response for ~ 5 seconds while the container is starting then back to no response.

I can ping the Gluetun container at all times.

Also have this in my post-rules.txt
