I want to make sure I understand your goal correctly. Here’s what I’m getting.
- You have a wire guard connection that you want to use for outbound traffic from your local LAN.
- You have a Debian box that serves at the client in this situation.
Here’s the part where I’m a little fuzzy
- You want to connect to your local LAN using another wire guard connection and have WAN requests routed from clients connecting to your LAN (via wire guard) out the wire guard connection mentioned in #1.
Did I get any part of that wrong?
Edit: NVM. I saw your response to another comment that sounds like this is exactly what you want.
This should be achievable via routing. I actually do the same thing. The main difference is all the work is done on my router which handles both wire guard connections and routing.
At the minimim you’re going to need:
- A NAT rule on your local router to port forward incoming wire guard requests on the WAN to your Debian box. **Assuming the Debian box is also the wire guard server.
- An iptables DSTNAT rule on your Debian box to route local traffic to the LAN gateway.
- An iptables DSTNAT rule on your Debian box to route outbound WAN traffic that does NOT originate from your Debian box to the gateway at the other end of the outbound wire guard connection.
Holy shit. I think you just found a valid use for LLM’s. OpenAI valuation intensifies
