I've been looking at various configurations of iptables, and I don't have a clear idea on how to do the following:
I have an application that sends UDP packets, and I would force the out bound packets to be sent via a specific interface. For example, I have a satellite link for the out going packets, but a ground link for the return packets. I have a program which works with a single link, and I'd like to have that program unaware that the stream is being split in the kernel. I have seen mention of a 'tee' feature for iptable filtering, but that's not quite what I want… since there is no need to duplicate the stream and send it two different ways. The problem I have is thinking about such things as how 'arp' works, and that if the satellite link sends an 'arp request', that interface will expect an 'arp-response', but that will be returned via the ground link path… Somewhere in my memory, I recall this sort of setup for remote locations that had a satellite down link, and a slow modem access for 'up link'. Any help would be appreciated.
