Create the "outside" interface on a subinterface?

[campbech1]

So I have, what I think is an easy question, but I think I'm overthinking it. See, too many thinks..

I have a circuit that will be delivered to a client next week and we are installing an ASA 5585x for them. They will have a circuit coming in with a few VLANs configured on it. One VLAN for the Internet and one for connectivity to another client.

So does the ASA allow you to create the "outside" interface on a subinterface?

Thanks.

Sure can...

Just have to make sure that you don't have 2 default routes configured on the ASA going to 2 different interfaces. This is not supported.

Hi,

It would be a normal interface.
