# IP Pool Configuration

IP address pools provide addresses for the NetScreen device when using L2TP tunnels and creating L2TP users. You first have to create IP address pools before you can configure L2TP users and L2TP tunnels.

Note: The L2TP pool addresses must be in a different subnet from those in the Trust zone.

### To Create a New IP Pool

1. On the IP Pools list page, click New, and then enter the necessary information:

IP Pool Name: Enter a name for the new IP Pool. Once configured, the name of this IP Pool appears in the IP Pool drop-down menu on the L2TP Default Settings page, the L2TP Tunnel configuration page, and on the L2TP User configuration page.

Start IP: Enter a starting IP address value.

End IP: Enter an ending IP address value.

2. Click OK to save the settings.
