I am looking for some policy routing script for linux that isn't a part of a firewall, there are tools like shorewall and others but I prefer something more simple.

I only need a script that can set a per-service preference on one of my two upstream connections, and failover nicely when one of the connections is down.

So far I could only find a script called netsane that can be found at google code ( and it's more or less what I need but it looks a bit abandoned. The script is largely based on this tutorial from Larc Does anyone know about more alternatives for this?

For anyone interested into this, I jumped into the code and made some contributions to the original source, it should work better with recent systems (I am trying it with debian squeeze) – Aseques Feb 9 '12 at 10:20

You may take a look at IGNWTools, which has some routing-policy for Chinese users, including ISP-based routes and anti-censorship routes, may help you as examples :)

After reading about that tool, it seems to me that it'd be complicated to adapt to my environment. – Aseques Feb 6 '12 at 13:41
:( so hope you'll find something more appropriate – Felix Yan Feb 6 '12 at 15:35
