Hoolio answered a similar post on iRules and SNAT'ing, perhaps it will get you going in the right direction:

when CLIENT_ACCEPTED {

 

 

Check if client is in 192.168.1.0/24 subnet

 

if {[IP::addr [IP::client_addr] equals 192.168.1.0/24]}{

 

 

Use the snatpool

 

snatpool snatpool_11.11.11.1

 

}

 

}
