Looking for a not equals

yes I have a default pool that things will fall through to. I just put up th snippet that I was unsure of.

Another question, if I use the log statement in the iRule one of the other posters said that this will be logged in /var/log/ltm , but I am not seeing the entries. I must be missing something.

  
 when HTTP_REQUEST {  
   if { [HTTP::cookie exists "mine"] } {  
      if { [[HTTP::cookie "mine"] starts_with "3" ] and not [IP::addr[IP::remote_addr] equals 10.1.1.0/255.255.255.0] } {  
        log "The cookie starts with 3" 
        pool bogus-onenode  
      } else {  
        log "Missed the cookie staring with 3" 
        pool failsafe  
      }  
   } else {  
     log "no cookie" 
     pool real-onenode  
   }  
 }
