xforward-for doesnt work

Below http request iRule displays real ip in system - > logs -- > local traffic when HTTP_REQUEST { if { [HTTP::header exists X-Forwarded-For] } { log local0. "Received XFF from [IP::client_addr]: [HTTP::header X-Forwarded-For]"

 

} }

 

but i don't see the incoming request landing on backend server even if i add the below irule.

 

when CLIENT_ACCEPTED {

 

set vip [IP::local_addr]:[TCP::local_port] } when SERVER_CONNECTED {

 

set client "[IP::client_addr]:[TCP::client_port]"

 

set node "[IP::server_addr]:[TCP::server_port]" log local0. "Client $client -> VIP: $vip -> Node: $node"

 

}

 

could you please let me know how to combine both http_request and client_accepted irule so that the logs would be displayed in system - > logs -- > local traffic

 

as

 

XFF IP -- > VIP -- > Backend Server IP
