access to docker container ports thru VPN Tunnel (as client)

[SuperMotzer]

Hello,

I use my synology as Wireguard client. The recommended routing rules:

PostUp = iptables -t nat -A POSTROUTING -o wg+ -j MASQUERADE
PreDown = iptables -t nat -D POSTROUTING -o wg+ -j MASQUERADE
are efficient for the ports of the host but not for the docker ports that are published at the host.
Means I can access to my containers on a local basis (192.168.xxx) but when I'm outside I can only access webserver, admin, SSH but none of my containers. Their ports are not visible.

Thank you for your help,
Cheers,
Stephan
