iRule Help: Pool Selection on VIP port basis

Pardon me if this one already posted... I need to configure VIP to listen on traffic on port range say "2000 to 5000" and the back end physical servers are listening on port 2000 to 5000. I created VIP with IP say 1.2.3.4:*AllPorts , and I created Pool with Member IP say 8.8.8.8:*AllPorts and applied following iRule which was posted in DEV Central Forum

 

 

when HTTP_REQUEST {

 

if { [ [[TCP::local_port] >=2000] and [[TCP::local_port] <=5000]] }

 

{ pool Exchange2010_CAS_POOL }

 

else { reject }

 

}

 

 

When I see statistics on F5, I see traffic coming in and OUT of VIP and I see traffic coming IN to Pool Member but I dont see traffic going OUT of Pool Member. I am not sure what is wrong? Is the iRule is incorrect or the Pool member should not be configured that way....Any help will be greatly appreciated. Thank you.

    Do you have SNAT enabled on the VS? What do you see in a tcpdump filtering on the VS or pool addresses (tcpdump -ni 0.0 -Xs0 host 1.2.3.4 or host 8.8.8.8)

     

     

    Also, if you want a quick reply, you could open a case with F5 Support.
