System wide SOCKS5 Proxy I connect to my Server on the internet using `ssh -D 3128 user@rootserver.com`. If I am right I thereby open a SOCKS v5 Proxy to my Server. Using Firefox and FoxyProxy I can now add this to my proxys and tunnel my HTTP-Traffic over it. Howsoever I'd like to use this SOCKS Proxy for all my traffic. Friends told me that they've seen this by modifying your route or using `iptables` howsoever I can't find anything about it.

`SOCKS5` is a protocol (i.e. in the application layer of OSI), so plain network-routing (e.g. via `iptables`) alone _won't do_. (It's probably necessary, but not sufficient.)

What you need is a _proxifier_. Without having tried it, `tun2socks`, allowing you to _"socksify TCP at the network layer"_ , looks promising (as does `proxychains`, without `iptables` but prefixing programs explicitly).

(Could `socat` be used here? This mentions `socat` for socksifying, but I'm unsure at the moment.)
