Hi Darshan,

the datagroup based version is more flexible regarding subnet mask length.

Using the following 'switch' based approach limits you to a fixed subnet mask length. 
when CLIENT_ACCEPTED {
    switch [IP::addr [IP::client_addr] mask 255.255.255.0] {
    10.10.1.0   { snat 10.232.232.1 }
    10.10.2.0   { snat 10.232.232.2 }
    10.10.3.0   { snat 10.232.232.3 }
    default     { snat 10.232.232.4 }
    }
}

Thanks,

Stephan
