Hi All,

I read in one of the doc that we can share IP address on shared interface on
different contexts. Is it correct? If yes then how packet classifier will
classify the packet?
Lets take an example: ASA has three contexts A, B and C. They are sharing
outside interface i.e. Giga0/0 with IP address. Internet router is attached
to ASA's outside interface. Now in this scenario how ASA will divert a
packet coming from internet to correct context from where connection is
originated?

One way is separate mac address for outside interface. But in this case,
returned packet will go to all contexts as they are having same outside ip
address.

Another way is NAT destination IP address. But in this case, destination IP
will be from outside ip address range only. So once again it will go to all
contexts.

Kindly help me in this case.

Regards,
D.M.Gore
