The problem is may be that you are using 2 devices for
one subnet. For many users it looks like a natural way to have
redundant setups. Wrong. Especially when rp_filter is 1 on these
interfaces.
IMO, the problem is may be in your RS. Just show us some
settings:
- which interface is used for default route in RS
- 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
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.
