Server A replies to a ping request to 1.2.3.42 coming from server B. Some
info below:

To answer your second question, we do not put one of the routable IPs on
eth2 of server A because the default gateway provided by the ISP is not on
the same network.

NB: currently if you assign IP within ip range 1.2.3.32/27 of server A to

I'm not sure what you mean here.  Do you mean assigning (for example)
1.2.3.34 to eth0 of server B and then trying to ping server A on 1.2.3.42?
