IP Interfaces

After you have configured the basic options for the internal IP interface, you can manage the security zones associated with the interface, or configure routing in the Advanced Options section. For details, see the following topics:

•“Manage Security Zones for IP Interfaces” on page 149

•“Configuring Routing for IP Interfaces” on page 150

External Interface: DHCP Configuration

If your ISP has told you to use DHCP, or you are connecting to a device that provides the IP configuration for the device using DHCP, select DHCP. With DHCP, you can confirm the configuration settings by requesting a DHCP lease. If the interface is down, DHCP attempts to auto-connect until the connection establishes.

Configure DHCP on the External IP interface

External Interface: PPTP Client Configuration

Select PPTP client if your ISP is using PPTP to provide the IP configuration for the device, or you wish to use a PPTP tunnel for all WAN traffic (to connect back to the main office site, for example). After configuring the PPTP client, you can confirm the settings by pressing the Connect button.

Note Use of a PPTP client requires the device to have a valid IP configuration for the external Virtual Interface on the local network. This IP configuration can be provided by DHCP or specified via the "Local IP" parameters as shown in Step 6.
