I have a server with wireguard in a container with host networking. I want to assign an ipv6 subnet for each peer (eg: fd42:413d:a91f:dd37::/64
) that the client (my laptop) can freely use all the addresses in that subnet and corresponding port ranges as a separate network interface. Meanwhile on the server, that exact same ip and port is routed to that specific client but through the tunnel.
Here’s an example:
-
Server config
[Interface] Address = fd42::1/128 ListenPort = 51820 PrivateKey = <key> [Peer] PublicKey = <key> AllowedIPs = fd42:413d:a91f:dd37::/64
-
Client config
[Interface] PrivateKey = <key> Address = fd42:413d:a91f:dd37::1/64 [Peer] PublicKey = <key> Endpoint = server.local:51820 AllowedIPs = fd42:413d::/32, fd42:413d:a91f:dd37::/64
-
Run a server on the client
python -m http.server 8080 --bind fd42:413d:a91f:dd37::1 -d dist
-
Access on the server
curl -svL http://[fd42:413d:a91f:dd37::1]:8080/
I can’t get step 4 to work. It’s also entirely possible that my lack of knowledge in networking is making me think this is even possible in the first place. Any help is appreciated!
It doesn’t have to be the same address, just one that I can be sure is associated with a specific peer.
Here’s what I see with
ip -6 route

I think I misunderstood how NAT works.
