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.
