Re: OT: VLAN Pairing (maybe on topic....)

Marc,

are you referring to the designs like: (all on same L3 switch)

vlan 200 (layer 2 only) -----> inside interface FW --> outside FW interface
(vlan 200 re-map to vlan 210) --------> vlan 210 L3 SVI
vlan 3400 (layer 2 only) ------> outside interface IPS ---> inside IPS
interface vlan 3410 ----> outside FW interface

Not sure is this is what you are speaking of, I just want to get on-point
first.

JS.
