Description:
When the internet connection fails communication to other company sites or partner companies is often interupted. Also cloud services are not available during an outage of the internet connection. Therefore it is recommended to use a separate internet connection as a backup, thus enabling it to be established during an outage of the main internet connection.
This article describes how to set up a backup connection for a Unified Firewall.
Requirements:
- LANCOM R&S® Unified Firewall with firmware as of version 10.2
- Configured and functional internet connection
- Additional internet connection as backup
- Web browser for configuring the Unified Firewall.
The following browsers are supported:- Google Chrome
- Chromium
- Mozilla Firefox
Procedure:
1) Set up an additional internet connection which serves as a backup connection for the existing one.
Use one of the following Knowledge Base articles depending on what kind of internet connection you have for the backup connection.
- Setting up an Internet connection with static address assignment on a LANCOM R&S®Unified Firewall (cable Internet or SDSL)
- Setting up an Internet connection with dynamic IP address assignment per DHCP on a LANCOM R&S®Unified Firewall (cable Internet)
- Setting up an ADSL connection without specifying a VLAN ID on a LANCOM R&S®Unified Firewall (PPPoE)
- Setting up an ADSL or VDSL connection with a specified VLAN ID on a LANCOM R&S®Unified Firewall (PPPoE)
2) Go to the internet connection created in step 1), change to the tab Failover and activate the option Use as backup connection.
3) Go to the menu Network → Connections → Network Connections and click on the "Pencil" symbol of the main internet connection (in this example the interface eth0 is used) to edit its settings.
4) Go to the tab Failover, select the internet connection created in step 1) as a Backup connection and add it via the "Plus" symbol.
5) The configuration of the backup connection is now complete.
