MRS on Border

MRS can be configured to separate user and server networks. This is achieved by the User IP setting, MRS uses one IP address towards the location (or users), and another towards the other locations (server network).

To configure the NAT location, make sure there is at least one MRS module available, and configure in the System Configurator the following items:

1. To create a location, choose Call Switching > Locations. For more information, see the System Configurator document and Managing Locations.

   • Enter Name and Description.

   • Select Network Address Translation (NAT).

   • To define the location contents, choose Users, and enter the users of the location. Alternatively use Network Elements, or IP Ranges.

   • To allocate the MRS module for this location, click Add New in the MRS Allocation block and define the following settings. After adding one MRS, click Save in the lower right corner of the block.

     • Choose the MRS module from the list.

     • Enter an integer number for the Priority, the setting is mandatory. If there is only one MRS module in the location, the priority value has no effect but it must be entered in all cases.

     • Enter the User IP address 10.1.2.1.

     • If nothing is defined for Maximum Number of Simultaneous NAT Streams, the default value is 100 is used. The value should be at least the same as the number of simultaneous NAT calls expected to be routed via this MRS.

   • Save your entries.

2. To enable NAT, choose Global Switching Settings > NAT, and check the Use NAT checkbox.
