Just to be clear, the interfaces are both of the form 152.3.172.*.

If for example they were reconfigured so that one was of the form
152.3.171.* and the other was of the form 152.3.172.& (say) then would the
problem just disappear?

That largely depends on your subnet mask and how your network is routed.
What is the output of `/sbin/ifconfig` with both interfaces up?

See below. The problem interface is eth0. The original one, which still seems to work Ok, is eth1.

Thanks.                                                          Faheem.
