    Additionally with the same i-rule can you change your VIP to performance layer 4 instead of standard and then check do a tcpdump to see whether the VIP is doing a 3way handshake.

    but we can access other ports. meaning the irules is not working well.

    You mean you can access the VIP on other port as well ? apart from the specified range 50000 - 60000 ?

     

    Can you paste the tcpdump output when you try connecting it from outside say TCP port 20.

    i think, since we are using all ports on the VIP, that's why we can acess all ports.

     

    can you give me the tcpdump command.
