iRule for Conditional SNAT

Hi,

Do you really need the SNAT pool, or you just need to definean IP address to SNAT on iRule?

e.g.

# Classic syntax
when CLIENT_ACCEPTED {
    if { [IP::client_addr] eq "10.10.10.1" || [IP::client_addr] eq "10.10.10.2" } {
        snat 10.214.214.148
    } else {
        snat 10.214.214.147
    }
}
 
# Short way
when CLIENT_ACCEPTED {
    if { "10.10.10.1, 10.10.10.2" contains [IP::client_addr] } {
        snat 10.214.214.148
    } else {
        snat 10.214.214.147
    }
}
 
# Expansive way, increase list when needed
when CLIENT_ACCEPTED {
    switch [IP::client_addr] {
        10.10.10.1 -
        10.10.10.2 {
            snat 10.214.214.148
        }
        default {
            snat 10.214.214.147
        }
    }
}

You must change line from "snat <IP ADDR>" to "snatpool <POOLNAME>" if you need to use a SNAT pool.

I hope it helps.
