Converting the on-premises appliance into a TCP relay

To convert the on-premises Endpoint Security (HX) appliance into a TCP relay for the cloud Endpoint Security (HX) server using the CLI:

Log in to the on-premises Endpoint Security (HX) appliance using the SSH protocol and the IP address or host name of the appliance's management interface.

Enable CLI configuration mode.

hostname > enable
hostname # configure terminal

Convert the on-premises Endpoint Security (HX) appliance into a TCP relay to the cloud Endpoint Security (HX) server:
```
hostname # hx rproxy relay <ip-address-or-host-name>
```
where <ip-address-or-host-name> is the host name or public IP address for the cloud Endpoint Security (HX) ecosystem. You collected this information for the cloud Endpoint Security (HX) ecosystem before the on-premises Endpoint Security (HX) appliance backup was uploaded to the cloud Endpoint Security (HX) server. See Recording the Server Address List Settings of the Cloud Endpoint Security Ecosystem.
Save your changes:
```
hostname (config) # write memory
```

If the Endpoint Security (HX) appliance is in relay mode when it is upgraded, relay mode must be re-enabled after the upgrade completes.
