Syntext on Irule for NATTING

Hi     I am writing an irule to do some natting (long story i know there are better ways). I know the switch statement has a limitation in the number of functions you can have it do, i.e. SNAT...

As you do SNAT in any case (value of c_nat will be 0 or 1), you can put it all in one switch statement, without the -glob. 

when CLIENT_ACCEPTED {
  switch [IP::remote_addr] {
     "10.X.X.5"  { snatpool SNATX member X.X.X.1 }
     "10.X.X.6"  { snatpool SNATX member X.X.X.2 }
     "10.X.X.7"  { snatpool SNATX member X.X.X.3 }
     "10.X.X.8"  { snatpool SNATX member X.X.X.4 }
     "10.X.X.9"  { snatpool SNATX member X.X.X.5 }
     "10.X.X.25" { snatpool SNATY member X.X.Y.1 }
     "10.X.X.26" { snatpool SNATY member X.X.Y.2 }
     default   { snatpool SNAT }
   }
   if this is your only pool, leave the statement here. Otherwise put it in the switch action 
   pool poo_2
}
