Dual ISPs - Dual Firewalls

Hello,

I am in in need of some help.  I haven't done this type of configuration before, but we're undergoing a network upgrade.

I'm a bit confused as to how this configuration should be setup, to work correctly.ATC_NEW2.jpg

The AT&T RTR and COMCAST RTR are provided and managed by the internet providers.  This setup should provide complete redundancy within the network.  The portion I am unsure about is between the two ISPs.  I don't believe I can use HSRP for FW1 and FW2 since they're on different IP subnets (public).  Any advise would be appreciated. 

Thanks,

GS

Hi

Are you looking for only failover or loadbalance too ? if you are  looking for failover only then it will work as you expected but there might be convergence issues at ISP cloud.
