Two ISP for default route with failover issues

Hi guys,

I have a clusterXL, in cloning group, ith two internet service providers and one ot them gave me a /30 network. To keep my VIP working was necessary create a different subnet that the ISP gave me.

Becouse that, isn´t possible to use ISP Redundancy. So, I tried to configure my default route with two gateways with different priorities. ISP 1 with priority 1 and ISP 2 with prioritie 2. All them have a "PING" enabled and "IP Reachability Detection" enabled with external addresses to test.

When my ISP with prioirty 1 fails, the backup ISP doens´t take on the internet requests from my network.

Are there some other configuration to do?

Do you see the route change if you check it via the CLI and how is NAT configured on the Gateway?

When the ISP with priority 1 fails, the default route disappear. The NAT is enabled on the gateway, "Hide internal networks behind..."

I configured this for customer last year and definitely works fine. I assume you are using primary/backup? Can you do some captures and traces to see why its failing when connections go to your secondary link?
