Next question should also be, "how are you pinging?" `ping` should
allow you to set the source interface of the outgoing packets w/ the
'-I' flag. I believe this should prevent the system from attempting
to decide which interface to source the traffic on. The `arping`
tool has a similar flag.
$ ping -I eth1 ip.ad.dr.ess
Additionally, are there other hosts already working on the private
backup network? If so can they reach the problem hosts? If you
attempt to ping from a working host to 10.254.250.226 do you see
incoming traffic via `tcpdump` and the proper ARP records in `arp -a`?
