How to Set Up a Primary and Backup Internet Connection Connected to SW

[cooperrocks78]

Hi,

We currently have 1 ISP and 1 internet connection going into our office.  We are setting up HA on 2 FortiGate firewalls but we only have 1 internet connection.  How can I set up a Cisco switch to split 1 internet circuit for a backup and primary internet connection for HA?

yes you can do that. configure 3 ports in cisco switch same VLAN (any vlan which you have not used in same switch for any other purpose) the connect one port to ISP router and other two ports to fortigate devices (WAN port).

Look at the below guide : its simple connect nothing changes here, just connect both Fortigate to WAN switch)
