Cisco ESA Deployment

[lakshmanarao.v]

Hello Everyone,

I have seen deployment guides of Cisco ESA stating that the ESA is to be deployed in the DMZ network

Can We deploy Cisco ESA and also the internal mail server in the same network ?

You can, but you need to make sure that email (inbound and outbound) flows through the ESA and nothing is direct to your email server. Putting ESA on the edge does make the deployment and future troubleshooting easier.

Hope it helps.
