Redirect Specific source network to specific pool member

Yes.

You could use something simple like this

 when RULE_INIT {
     set static::bypass_LB_net "10.20.118.0/24"
     set static::bypass_LB_member "10.210.34.100"
 }

 when CLIENT_ACCEPTED {

     set currentpool [LB::server pool]

    if { [IP::addr [IP::client_addr] equals $static::bypass_LB_net] } { 
        pool $currentpool member $static::bypass_LB_member
    }
 }

or if you want to be more dynamic, use a datagroup where you define which network you want to send to which pool member.

 ltm data-group internal bypass_LB_DG {
     partition test
     records {
         10.10.20.0/24 {
             data 10.110.30.43
         }
         10.20.118.0/24 {
             data 10.210.34.100
         }
     }
     type ip
 }

 ltm rule bypass_LB_irule {
 when CLIENT_ACCEPTED {

    set currentpool [LB::server pool]

    set poolmember [class match -value [IP::client_addr] equals bypass_LB_DG]

    if { $poolmember ne "" } {
             some errorhandling is always good to have :)
        if { [catch {

                pool $currentpool member $poolmember

            } poolselectstatus] != 0} {
                    log local0. "Error selecting member $poolmember $poolselectstatus"
                }   
    }
 }
 }

These are a bit untested but hopefully you can get something out of them 🙂
