Connect Active/Standby cluster to single ASA

[Eric Snijders]

Hi All,

I'll be installing a new (single) Cisco ASA soon, and i need to connect that directly to a Active/Standby Cluster. How should i configure this on the new ASA Side? Should i create a "Redundant Interface" and connect the Active firewall to the primary port on the new ASA?

Thanks in advance!

You need to connect the new ASA to both old ASAs. Best way is to have a switch between these three devices.

Hi Karsten,

Thanks for the advice. If i would want to connect the new ASA to both other ASA's, how should i configure the port(s) on the new ASA? Should i configure them as a Redundant Interface?

Do you plan to make the switch in between the ASAs redundant? Then a redundant interface is a good choice. If the switch will be a single device, then a single interface on the new ASA should be fine.
