How to configure Virtual Gateways?

Cisco Email Security Appliance (ESA)

The Virtual Gateway technology enables users to separate the Cisco Email Security Appliance into multiple
Virtual Gateway addresses, from which to send and receive emails. Each Virtual Gateway address is given a
distinct IP address, hostname and domain, and email queue.

Before setting up the Cisco Email Security Appliance Virtual Gateway addresses, you must allocate a set of IP
addresses that will be used to send emails from. You should also ensure proper configuration of your DNS
servers so that the IP addresses resolve to valid hostnames.

Create new IP interfaces with the IP/hostname pairs from the Network > IP Interfaces page in the
WebUI or the interfaceconfig command in the CLI.

• 

Go to the CLI and group the IP interfaces within the interfaceconfig command:

• 

example.lab> interfaceconfig

Currently configured interfaces:
1. data1 (10.66.71.12/24 on Data 1: example.lab)
2. Domain1 (192.168.1.1/24 on Data 1: domain1.lab)
3. Domain2 (192.168.2.1/24, 2001:db8::/32 on Data 1: domain2.lab)

Choose the operation you want to perform:
− NEW − Create a new interface.
− EDIT − Modify an interface.
− GROUPS − Define interface groups.
− DELETE − Remove an interface.
