How can i create an iRule for one VIP with multiple service ports.

Will this syntax be correct? With the VIP destiation set to 0?

when CLIENT_ACCEPTED { if {([TCP::local_port] == 443 )} { pool pool_443 } if {([TCP::local_port] == 5554 )} { pool pool_5443 } if {([TCP::local_port] == 8080 )} { pool pool_8080 } if {([TCP::local_port] == 4900 )} { pool pool_4900 } if {([TCP::local_port] == 4889 )} { pool pool_4889 } if {([TCP::local_port] == 8081 )} { pool pool_8081 } if {([TCP::local_port] == 7301 )} { pool pool_7301 } if {([TCP::local_port] == 7302 )} { pool pool_7302 } if {([TCP::local_port] == 7788 )} { pool pool_7788 } if {([TCP::local_port] == 7799 )} { pool pool_7799 } if {([TCP::local_port] == 9851 )} { pool pool_9851 } if {([TCP::local_port] == 9788 )} { pool pool_9788 } else reject }

Thanks for the info

You can try with this code:

    when CLIENT_ACCEPTED {
     if {([TCP::local_port] == 443 )} { pool pool_443 } 
    elseif {([TCP::local_port] == 5554 )} { pool pool_5443 }    
    elseif {([TCP::local_port] == 8080 )} { pool pool_8080 }
    elseif {([TCP::local_port] == 4900 )} { pool pool_4900 }
    elseif {([TCP::local_port] == 4889 )} { pool pool_4889 }
    elseif {([TCP::local_port] == 8081 )} { pool pool_8081 }
    elseif {([TCP::local_port] == 7301 )} { pool pool_7301 }
    elseif {([TCP::local_port] == 7302 )} { pool pool_7302 }
    elseif {([TCP::local_port] == 7788 )} { pool pool_7788 }
    elseif {([TCP::local_port] == 7799 )} { pool pool_7799 }
    elseif {([TCP::local_port] == 9851 )} { pool pool_9851 }
    elseif {([TCP::local_port] == 9788 )} { pool pool_9788 }
    else { reject }
 } 

$1 * use a data group containing pool name as value. You can add as many port in datagroup...

        ltm data-group internal DG_TCP { 
        records { 
        443 {pool_443} 
        5554 {pool_5554} 
        8080 {Pool_8080}
        4900 {pool_4900}
        4889 {pool_4889}
        xxxx {pool_xxx}
             } 
        type string 
        }

        when CLIENT_ACCEPTED {
        if {[set pool [class match -value [TCP::local_port] equals "DG_TCP"]] ne ""} {
         pool $pool
        } else {
            reject
        }
    }

cheers...

That's clever, but because adding and subtracting pool want change i'll use the first iRule suggested. Thanks for the prompt input.

For the number of comparisons you are making, you really should look into the 'switch' structure.
