wan, vlan, tagged, untagged
My router is temporarily far from my firebox. They are separated by a couple of managed switches.
I need help on how to configure the external interface of the firebox.
The router sends untagged traffic to port1[untagged with pvid 29] on switch1.
Switch1 and switch2 are in trunk with a tagged port each one, for vlan 29 and others.
How do I configure switch2 egress port linked to my firebox external interface eth1?
A) switch2 egress tagged for 29 and firebox eth1 configured as vlan type added to vlan 29.
switch2 egress untagged with pvid 29, firebox' eth1 untagged and configured as external.
