I tried but I got this error:

# arping -U -I eth1 80.23.252.59
bind: Cannot assign requested address

Probably because of the tight security on MNF.

Probably another source of troubles comes from the fact that I keep on
receiving martian packets from the network address

gw kernel: martian source 80.23.252.59 from 80.23.252.56, on dev
  eth1
gw kernel: martian source 80.23.252.61 from 80.23.252.56, on dev
  eth1

as you probably understood I am not a routing expert but I guess that
that can poison the arp table of the router and the firewal.
