I am not sure I understand what you are trying to do, but in general:

you cannot have two machine us ethe same IP address, it just does not
work; whether you use bridge or not.

Try to work out your problems using IP address first and something
simple like ping.

Use tcpdump, you will most certainly see all packets going to machine
B instead of machine A.
