2. Packet from WAN to LAN
2.1.
WAN port receives a packet with locked address PC3.
2.2.
IP178C/IP178CH adds a PVID equal to 2 and forwards the packet to CPU.
2.3.
CPU updates the DA, replaces PVID with 1 and sends it to IP178C/IP178CH.
2.4.
IP178C/IP178CH learns the SA.
2.5.
IP178C/IP178CH forwards the packet to port0 according to the DA.
