NimbostratusUnexpected UIE entries in persistence table ; Client Addr = Node Addr
I have configured a number of VIPs on our BipIP v 11.4.0 using UIE cookie persistence with an iRule that checks cookie value for a number of web applications.
Testing persistence seems to work fine but when I check the persistence table I see a number of records where the source address is matching one of the node addresses and not the source address of the client. The value matches the cookie value in the browser of the real client. Is this expected behavior or is something else going on here? there are no proxy servers in this mix.

is it possible that server (node) has accessed the virtual server?
Glenn_Nummy_134Hi, thanks for your quick reply. I tested again while checking the connection table: 'show sys connection cs-server-addr 192.168.8.200' And it shows connections only from the client as expected, so I cant see any reason for the persistence record to show source address to be the node address.
Also I tested the same rule using Source Address persistence instead of UIE and it shows the correct client address in the persistence records.
We need to continue use cookie persistence as the clients will soon be behind a secure gateway so their real source address will not be visible from the BigIP.
