Question : How to forward all https request  by using one isp line

Hi,
We have 2 isp line , which is connected to a Load balancing router.( if you can look at picture i attached, you would know,how I set up my network)

problem is : some web sites , suppose this - https://75.125.98.114:8443/
when  i am clicking this address, its opening the page, so i can say 8443 ports are open from my side. now problem is , when i am tying user name and password, its just keep logging me off, i know why :
because, https request is going between  2 isp line, so web hosting company,they put some sort of security , and cookie is seeing some times request is tomming via line 1 and some times line2. so he thinks , there is some problem , so it just log me off.

Now, if any one can tell me, if there is any way , so that, i can sent all Https request via one ISP line.

fosiul01, hi

I have some questions about your topology:
1) Are you using 193.132.234.x as an internal LAN or it's your internet addresses?
2) I don't see 2 ISPs connected to your IPCop. Which lines are local and which are external?

IPCop itself doesn't perform load balancing. What product (may be for IPCop) are you using to do it, how it's configured and what load balancing algorithm is used?
