(admin: I ask excuse for having posted this in the erroneous thread, "remote hosting". I don't wanto to make cross-posting, simply I don't know how to delete the other post)

I have a problem with a local director Cisco LDIR410, I hope anyway that it can apply to any kind of load balancing.

The LDIR makes http load balancing among three front-end.
The LDIR is configured that sessions are solved by the IP of the user, keeping one hour the IP redirect to the same front-end of the pool.

One user has this problem: the local director distribute his packet on more than one front-end randomly. The user has this problem using and not using his proxy, and is connected via T1 and has a Cisco Router.

Obviously, all connections of the user breaks in few time.

Anybody can help please?
Thank you.
