Containers outside the DelugeVPN network cannot access containers under DelugeVPN

[joelstitch]

I have DelugeVPN running as a stack and I have a few containers under its network to be able to run under the VPN. My issue right now is that I cannot get a Plex container to access the IP of the container Cabernet. Basically Cabernet works as a tuner and plex is supposed to be able to access that tuner and play some channels but Plex is not able to access it. So my question is what can I do so other containers outside the DelugeVPN network can access containers inside its network?
