Traffic Flow through a firewall

                   When a packet enters a firewall on the Internet interface and exits on the inside; what is the source address of that packet on the internal network? Does it keeps it original address or is it the inside interface address?

Traffic Flow through a firewall

Hi,

The source IP address remains unchanged in any normal setup.

It   might be changed in some more special setup but 99% of the time I  would  say there is no need to NAT the source address of a connection  coming  from External to Internal network.
