Hello Julian ;),
IMO, the problem is may be in your RS. Just show us some
settings:
Yes, this is also my opinion now that I know it is only _one_ machine.
- which interface is used for default route in RS
eth0. He just sent me the routing information off-list. I will cc you
with my reply.
- how rp_filter is set for eth0 and eth1 in RS:
cat /proc/sys/net/ipv4/conf/eth0/rp_filter
cat /proc/sys/net/ipv4/conf/eth1/rp_filter
I also suspect a problem here with asymmetric routing.
Just make a tcpdump and check whether packets to
~.18 appear on eth0 (not on eth1 as expected). Or just make
~.18 alias on eth0.
I'm working offlist with him right now, I think I will cc you in the
replies so we can solve the problem faster.
Best regards,
Roberto Nibali, ratz
