Hi Darshan, I will look for a working example based on switch.

Another alternative is using datagroups (classes).

In the following example an external datagroup (file based) is used: 
[root@ltmve:Active] config  cat dg_snat_mapping_ip
host 10.100.100.20 := "10.100.100.120",
host 10.100.100.21 := "10.100.100.121",
host 10.100.100.22 := "10.100.100.122",
host 10.100.100.23 := "10.100.100.123",
host 10.100.100.24 := "10.100.100.124",
network 10.100.100.0/24 := "10.100.100.126",

[root@ltmve:Active] config  bigpipe class ext_dg_snat list
class ext_dg_snat {
    type ip
    filename "/config/dg_snat_mapping_ip"
    mode read
    separator ":="
}

when CLIENT_ACCEPTED {
    set entry [class match -value [IP::client_addr] equals ext_dg_snat]
    if { $entry ne "" } {
        snat $entry
    }
    else {
        log local0. "No SNAT for [IP::client_addr]"
    }
}

Thanks,

Stephan
