Fortigate High Availability – Active/Active – Part 2 – Implementation

In Part 1 we got the prerequisites sorted out for the HA (removed all PPPoE or DHCP address assignment from the FG boxes and VLANed a switch to split the inputs between both boxes). Part 2 is considerably easier, the cabling had been done for the VLANs now we had to designate 2x ports as our cluster comms ports, I chose port1 and port2 on each box, each given a weight of 50:...

The PPPoE Problem The main problem was that both the internet connections used PPPoE for address assignment and auth - I had taken care of one of these previously as it was a simple ADSL link our Fortigate units didn’t allow for so we had a Cisco 837 ↗ box to terminate the PPPoE on a virtual interface and unnumber the static external IP to an internal interface....
