I've stumbled across something that looks like a bug in the IP
stack in linux relating to source routing.
Check /proc/sys/net/ipv4/conf/*/rp_filter on A.
It was previously 0, I changed it to 1 and got the same results.
Are you able to successfully perform the tests I specified?
(I assume you are, since you recommended a fix to me).
What are your network settings?
