I'm trying to create two routes --
Send all packets with IP protocol version 100 to 184.108.40.206 (via device eth1) Send all other IP packets to 220.127.116.11 (via device eth2)
Reviewing the man pages of ip-route and ip-rules, it seems like I should be able to do this, but I haven't been able to figure out the correct syntax.
This article has an example of how to setup a policy-based routing, but it's based on source IP address, not protocol number: http://blog.scottlowe.org/2013/05/29/a-quick-introduction-to-linux-policy-routing/
Is it possible to create protocol-based routing rules?
