To use the 6350-SR's cellular modem in tandem with its primary WAN Ethernet port, but only allow certain IP
addresses access to the cellular modem's Internet connection.
SeSetuptup
This article assumes the LAN ports are operating under default settings, which provide DHCP connectivity to devices
connected to the 6350-SR's LAN ports. For more details on the default settings of the 6350-SR, see the
DefDefaultault
SeSetttingstings
section of the 6350-SR User's Manual.
For this setup, you will need the 6350-SR with both a primary WAN Ethernet connection, and a cellular modem
connection.
You will also need to configure a static IP address on any client devices you want to allow access to the cellular
modem connection.
SampleSample
The sample configuration below shows a 6350-SR with two Internet connections: a cellular-based WAN connection
through the 6350-SR's modem, and a broadband-based WAN connection through the 6350-SR's WAN Ethernet port.
This set setup shows two client devices on a 6350-SR's LAN ports, a media PC and a laptop. The media PC is
configured with a static IP address of 192.168.0.99, and the laptop is getting its IP address via DHCP from the 6350-SR.
The policy-based routing we are going to setup will accomplish the following.
1. The 6350-SR uses the Ethernet WAN as its primary interface.
2. The 6350-SR has a cellular modem connection, used as a secondary WAN interface.
3. All tra/ic from the media PC will always go through the cellular modem WAN interface.
4. Any tra/ic from other LAN devices should go through the Ethernet WAN connection.
5. If the Ethernet WAN connection is down, the 6350-SR should drop any pac ets from LAN devices, excluding
pac ets from the media PC, and prevent them from going out the cellular modem interface.
