Preliminary Data Sheet
Operation
1.
Packet from LAN to WAN
1.1. PC0 sends a packet to a LAN port with SA equal to PC0 and PVID equal to 1.
1.2. IP178C forwards the packet to CPU with PVID equal to 1.
1.3. CPU replaces the SA with locked address PC3, replaces PVID with 2 and sends it to IP178C.
1.4. IP178C forwards the packet to port7 (WAN port).
