Cookie problem with load-balanced adsl lines

Hi All

I'm having a problem at one of our sites that I believe to be down to the fact they use multiple load balanced adsl lines. Users are being consistently logged off from websites they have recently logged into. I have checked to see that they haven't exceeded the website timeouts, cookies have been cleared etc all to no avail. I suspect it's down to the website requests going out on different IPs and this confusing the website at the other end. Does this sound feasible,  and if so is there any way of forcing users stay on the ip address the original request was made from?

Any help greatly appreciated as it's making my brain hurt.

p.s - sorry forgot to mention that the load balancing router is a Draytek Vigor 2820

I must admit that I haven't used the Draytek router, but I was interested in your question because load balancing is one of the areas I wok most with..
When I read the user guide, found at http://www.draytek.co.uk/support/downloads.html, I see on page 60 that you can configure which inside IP-address range goes out on which WAN interface. If you have done that there won't be different source IP-addresses.
Could you verify that it is configured with relevant source addresses?
