Is it possible to configure clustering on different IP subents, either for load sharing or active/passive

I.e. one firewall located on site A another in Site B

Not sure I understand your requirements here.

Can you elaborate a little?  Please give an example using a basic diagram with networks listed at each site.

Hi,

I have attached diagram 2 sites with replica hardware in each site, it a DR senario but I want to loadshare between each site. The Ip's are fake but it will be the same concept.  The idea is if one firewall fails the other site will take the load without have 2 firewalls in each site

Each site will be on a different subnet, so I don't think this is possibe as the default gateway of the router connecting the LAN, will be pointing to the firewall which will be on a differnet subnet, although I am not sure

Thats a lot clearer thanks.

In short, given this deployment, then no, you cannot cluster these devices.

Reasons include:

1.  Multiple WAN connections can be catered for using ISP redundancy, but this cannot be actioned over a cluster in different sites
2.  Each cluster interface needs to be in the same subnet to allow for the cluster IP creation.

If you had full layer 2 connectivity between each site and kept the same subnets on each side, you can then cluster across 2 sites, but the main requirement is layer2 connectivity,

Thanks

Layer 2 is still a Possibility.  Have not decided on Layer 2 or layer 3 connecting the sites
