Hi Team

If ACI has been integrated into the data center (DC) farm and a DC firewall is present, and all server gateways are currently terminated within the firewall, the question arises as to whether the server gateway should be defined in the firewall or within the ACI framework during the onboarding process.

Hi @mahmoodkhd 

We would recommend migrating gateway to ACI for features like Pervasive Gateway. You can plan gateway migration from firewall to ACI, Initially by extending L2out from ACI to traditional network and ACI BD running in L2 mode. Once all (or the majority of) the workloads belonging to the IP subnet are migrated into the Cisco ACI fabric, it is then possible to also migrate the default gateway into the Cisco ACI domain. This migration is done by turning on Cisco ACI routing in the bridge domain and de-configuring the default gateway function on the brownfield network devices.

Please use below default gateway migration consideration document:

Hi @ansuri ,

 

I value your thoughtful input. Nevertheless, if I were to relocate the Gateway from the Firewall to Cisco ACI, how can I ensure that the Firewall's UTM (Unified Threat Management) features are still in effect?

Furthermore, it's worth noting that in this scenario, the Firewall may become redundant. Additionally, considering that Cisco ACI is not primarily designed for security purposes, how can we guarantee the flawless operation of the Data Center (DC) Firewall?

Hi @mahmoodkhd,

You can use ACI PBR functionality, for adding L4-L7 devices to data path for applying FW related functionalities and utilising ACI L3 benefits discussed.  

Please go through ACI functionality of L4-L7 Service insertion
