The usage should be:
bind to src IP from eth0 and connect to local IP on eth1
Be ready, there can be something totally wrong.
I'm avoiding the arp_filter changes. The setup uses
asymmetric routing so better use arp_filter=0 or other
ARP filtering tools that can restrict our ARP replies
only via the desired device.
I want to avoid strange(r) routing configurations, as I'm already
using lots of routing tricks, and don't want to confuse matters
more. I also turn on arp filtering to ensure the arps go out the
right interface currently.
You should be able to easily test most of the changes your code
if you have a machine with two ethernet interfaces and a loopback
My requirements are:
1) Both ethernet ports communicate over the exernal link, UDP & IP traffic.
Third-party programs if possible, thus I set the flag on the interface in
my patch, not on an individual socket, though I do have to BINDTODEVICE and
policy-base base route to get things working right...
1b) Allow both same-subnet comm (eth1 & eth2 are on same subnet), and also
routed traffic (eth1 & eth2 have their own default router, similar to the
previously discussed routing setup)
2) Allow normal non-looped communication on the ports, including policy-based
based on source addr.
