RPC iRule

All,     I am new to this for sure. I am trying to do an iRule that will allow RPC traffic to pass to a single VIP with one pool associated to it. I have tried the two iRules below with ...

As Humphrey is hinting at, using the forward command (Click here) will bypass load balancing and cause LTM to send the packets to the same IP and port that the client requested. So you wouldn't want to use this on a standard IP VIP if you want the request to be load balanced to the pool. If you are wanting to use a pool, you can change the iRule slightly: 

 
 when CLIENT_ACCEPTED { 
    if { [TCP::local_port] == 135 or ( [TCP::local_port] >= 1024 and [TCP::local_port] < 65534 ) } { 
  
        Do nothing.  The default pool on the VIP will be used. 
  
    } else { 
        Drop the packets. 
       discard 
    } 
 }
