Routing for local interfaces
Posted on 2001-09-04
I am trying to test some devices attached to serial ports on my Linux box. I can establish PPP connections to a remote machine (which I don't control). Each PPP connection has the same remote IP address but each local IP address is unique.
My question is: How can I route packets to one of my PPP addresses through my ethernet interface and vise versa?
It seems as though the kernel sees that the outgoing packet is destined for a local interface and immediately chooses the 'lo' interface. I have tried bringing down the 'lo' interface and the result is that I cannot ping any of my own interfaces.
I am using RH7.1 with a 2.4.7 kernel built with RH's i686 configuration except that Policy Based Routing has been added.
