I'ma bit of a network newbie, so apologies for the inaccurate vocabulary.
Say I have a device connected by IP over USB to my computer (running Ubuntu), that connects to 10.0.0.1. I configured my Ubuntu's Wifi over USB so that my computer's IP on that connection is 10.0.0.1, but I would actually like to redirect all traffic (on all ports) to another server, and just use my computer as a proxy.
I played around with some solutions, but my lack of familiarity with network concepts is slowing me down (I spend too much time looking stuff up, and the documentation is often a bit lacking). I'm not even sure if I want to set up a proxy, a firewall (I don't think so), or use the routing tables. What I want to do sounds pretty simple ("redirect anything coming from IP over USB to that server over there"). So is there a standard way of doing that? iptables? squid? ufw?
