Can you remove the 'forward' command. If that doesn't work, add a bit more logging and another 'else' statement like so; 


when CLIENT_ACCEPTED {
 This iRule would NAT the source IP in the DG_SRC and match it to a destination in DG_DEST
 and then snat to the snatpool defined in DG_DST as the value corresponding to the name.
 if { [class match [IP::client_addr] equals "DG_SRC" ] } {
  set snatip [class match -value [IP::local_addr] equals "DG_DST" ]]
  if { not ($snatip equals "") } {
   log local0. "[IP::client_addr] going to [IP::local_addr] got Natted to $snatip"
   snat $snatip
   return
   }
   else
   log local0. "SNAT IP was empty"
 }
 else {
log local0. "[IP::client_addr] going to [IP::local_addr] did NOT get Natted!!!"
}
}
