You must take into account the following information:
If there is a gateway connecting the Command Center to the CommServe computer, make sure to provide the fully qualified domain name of the gateway (for example, gateway.gatewayservices.com)
The host name of the proxy computer must be resolvable from outside of the perimeter network and inside the local network
Make sure port 8403 is open for connections from outside of the perimeter network and inside the local network
From the navigation pane, go to Manage > Servers.
The Servers page appears.
In the upper-right, click Add gateway.
The Add gateway dialog box appears.
In the Host Name box, enter the host name.
In the Server Name box, enter the name of the gateway server.
