Can we have multiple SNAT pools configured under a single VIP?

I have a little situation here, we have a VIP that contains 4 nodes present at two different locations (2 nodes in A location and other 2 nodes in B location), having different subnets (we have separate routes to reach each location). What we want to achieve here is to have two different SNAT pools under a single VIP, each dedicated for each subnet.

let us say, I have 2 nodes under subnet 10.0.0.0/24 and 2 nodes under 20.0.0.0/24 such that traffic uses SNAT POOLs used: SNAT-1-->members--> 11.1.1.1 & 11.1.1.2 to reach nodes 10.0.0.0/24. SNAT-2-->members--> 12.1.1.1 & 12.1.1.2 to reach nodes 20.0.0.0/24.

How can we have irule modified for this particular case? Any help would be appreciated. Thanks!

This is pretty straightforward with an iRule:

when LB_SELECTED {
  if { [IP::addr [LB::server addr] equals 10.0.0.0/24] } {
    snatpool snat-1
  } else if { [IP::addr [LB::server addr] equals 10.0.0.0/24] } {
      snatpool snat-2
  }
}

Once the load balancing algorithm has determined the pool member, you can access that address with LB::server in the LB_SELECTED event, and once you compare it to your specified subnets, apply the snatpool accordingly.
