URL rewrite through iRule

Hi Sunnyman,

This will work;

if { [IP::addr [IP::client_addr] equals 1.1.1.1] || [IP::addr [IP::client_addr] equals 1.1.1.2} { 
    SNAT with 1.1.1.100
    snatpool VM_SNAT_POOL_1_1_1_100
} elseif { [IP::addr [IP::client_addr] equals 1.1.1.11] || [IP::addr [IP::client_addr] equals 1.1.1.12} { 
    SNAT with 1.1.1.100
    snatpool VM_SNAT_POOL_1_1_1_200
} 

But that's not a very scalable way of doing it if your list is going to grow. If it's going to grow then use an address datagroup, with values snatpool names, which you can use like this

snatpool [class match -value [IP::remote_addr] equals dg_sunnyman_snatpools]

or more correctly;

set snatpool [class match -value [IP::remote_addr] equals dg_sunnyman_snatpools]
if {$snatpool ne "") {
    snatpool $snatpool
 }
