ISP Redundancy on Checkpoint R75.45 Gaia – does not work

I installed R75.45 Gaia on a UTM-1 270 appliance recently, installation from USB went fine and performance was adequate with a low load, VPN, default IPS and a short QOS rule set.

In order to support a degree of resilience we’re using ISP Redundancy at all sites with multiple internet connections, despite configuring this site identically I was not able to get the failover to work. Usually, the script cp_isp_update runs and updates the gateways default route to match that of the secondary ISP, however when i tested this on R75.45 the route was not updated when primary was disconnected.

I contacted Checkpoint support and was informed that ISP Redundancy does not work in either version of Gaia, R75.45 or R75.40 – however there is a patch available for R75.40 if you contact them and reference this sk. I applied this patch on 75.40 but still didn’t see the solution work as expected so instead deployed R75.30 as I have at other ISP redundant sites.

I should also mention that my in no way scientific, cursory observations indicated that load on the CPU was much lower (15-20pc lower) on SPLAT (with 75.30) than on either version of GAIA. Something to bear in mind for older appliances like the UTM-1 270.
