Proxy port 3478 to another device?

[Azuriye]

Keeping this short and simple. I have a lan device which is listening on all ports and is connected to a VPN offshore. Is there anyway to route traffic from port 3478 from all my LAN devices to the device where my VPN is being hosted at? PBR seems to do this much easier but it looks like it only supports binding to a network adapter instead of forwarding it to another client.

This seems close enough to what I need. Marking this solved.

Transparent Proxy Routing

I’m not a PBR expert, so that may be true (or maybe it has more features now). That said, you could put the pi on another subnet such that you can use PBR via an interface to get to the pi. There is no reason that the pi really needs to be on the same l2 subnet as your client devices. Another approach could be to make your pi into the main router and then your c6 could be a dumb ap. This will greatly simplify the routing as it will all be handled by a single gateway.
