Ports and interfaces on SN160(W) and SN-S-Series firewalls

SN160(W) firewalls

Port no. 1 2 3 4 5
Interface WAN/out LAN/in

SN160(W) firewalls treat ports 2 to 5 (LAN/in interface) as a single interface, as they behave in the same way as a 4-port Gigabit Ethernet network switch.

SN-S-Series firewalls

Port no. 1 2 3 4
Interface WAN/out LAN/in dmz1 dmz2
Port no. 5 6 7 8 9 (fiber)
Interface dmz3 dmz4 dmz5 dmz6 dmz7

Only port 2 corresponds to the LAN/in interface: there is no longer any internal switch that groups ports 2 to 8 as a single interface.
