| * When running nftables to stop leakage of vpn it was found that the docker networking cause failure. Docker use loop address 127.0.0.11 to resolve its dns queries and then refers to the nominated local dns. See ''/etc/resolv.conf''. The docker documentation states that the user should not directly modify the resolv.conf file as it may adversely affect docker performance. As the openvpn program rewrites resolv.conf anyway I decided to do the same in a oneshot to point dns directly . | * When running nftables to stop leakage of vpn it was found that the docker networking cause failure.

I subsequently remembered the basics of UNIX the /etc/hosts file, this is the lowest level DNS on every machine. I simply added the relevant Private VPN end hosts files in here and this worked a beaut. |

| As described in the vpn section [[https://wiki.kptree.net/doku.php?id=tech_notes:docker-deluge#openvpn_setup|openvpn setup]], I decided to go with the docker macvlan network setup. This needs to be separately created and can then be called up when the container is run. A static ip address can be assigned when run. | As described in the vpn section [[https://wiki.kptree.net/doku.php?id=docker_notes:docker-deluge#openvpn_setup|openvpn setup]], I decided to go with the docker macvlan network setup.
