# Configure IP Translations

The MBG server receives messages from the ICP telling it to stream voice traffic to a particular IP address. There are some situations where you need to stream to a different IP address.

For example:

- If there are multiple servers in the DMZ, a call from one set on MBG1 to another set on MBG2 will have no audio path. In this case, you would configure IP Translation for all servers, specifying the relationship between their public addresses and their private DMZ addresses.

- If Server A is streaming to Server B in a DMZ at a remote office, voice traffic for calls between the sets on these servers would stream over the Internet because the ICP uses the public IP address of the servers. In this case, you would configure IP Translation to substitute the private address of Server B for its public address (and make sure it is routable from Server A).

To configure IP Translation:

1. On the MBG main page, click the System configuration tab and then click IP Translations.

2. Click Add new rule.

3. In the Destination address field, enter the IP address that the ICP uses to stream traffic (for example, the public IP of the server).

4. In the Translation address field, enter the IP address to which you want to divert the traffic (for example, the private IP of the server).

5. Click Save.
