Source Address Persistence with multiple ports

I have one virtual IP with the same pool members but are using multiple ports.The ports are 3446, 3447,7889,7990. I applied an iRule so it will persist looking into the ip address and the port being used. certain issues arise using the irule:

 

- no statistics appears on the pool members and also on the persistence records

 

- when a user log-in using 3446, then he tries to log-in using 3447 the session for 3446 will be logged off.but this does not happen when directly accessing server.

 

please check the irule:

 

when CLIENT_ACCEPTED {

 

set LB port based on requested port

 

switch [TCP::local_port] {

 

3446 {set port 3446}

 

3447 {set port 3447} }

 

log local0. "\$port = $port"

 

check for existing persistence record

 

if it exists, directly select node by address:port

 

set persist "[IP::client_addr]"

 

log local0. "\$persist = $persist"

 

set server [session lookup uie [list $persist]]

 

log local0. "\$server =$server"

 

if {($server != "") && ($port != "")}{ node $server $port

 

log local0. "persisting [IP::client_addr]:[TCP::client_port] to $server:$port" }

 

else {

 

log local0. "no persist connection" }

 

}

 

when LB_SELECTED {

 

add session table entry (5 min timeout)

 

log local0. "server in selected = $server" if {$server >= "1"}{

 

log local0. "persist an forward to = $server" }

 

else { set server [LB::server addr]

 

if {$server != ""}{ session add uie [list $persist] $server 1800

 

log local0. "add persitence record: $persist $server :$port 1800" }

 

else { log local0. "no server selected" } }

 

 

 

I hope anyone can help me on this one. Thank you.
