•
Destination - Packets passing through the NAT on the way back to the switch managed LAN are searched
against to the records kept by the NAT engine. There the destination IP address is changed back to the specific
internal private class IP address in order to reach the LAN over the switch managed network.
6. Enter the
Local Address
