Some web sites actually use the IP address as a security measure, to make sure someone isn't hijacking the session they require the IP address to stay the same. Your load balancer, of course, isn't doing that and causing the problem. It doesn't actually have anything to do with SSL, though I doubt you'd ever find a site doing this kind of security that DIDN'T have SSL.
- The problem is likely related to the TYPE of load-balancing you are doing. Most often, it is Round-Robin (ie: distributing the outbound traffic loads across ALL available interfaces to maximise throughput).
- Beware that Merlin has no control over Dual WAN, so issues will need to be reported directly to Asus. The main issue I noticed when using Dual WAN in load balancing mode is occasionally slow page loading time, failing to load assets, switching between modems at inappropriate times or not loading at all.

So, you need to tell your Linksys that whenever you're access the IP addresses associated with that bank to stay on one or the other ISP. Use NSLOOKUP, then type in the host FQDN (secure.thatbank.com) that the user uses to access that site. That'll give up all the IP addresses used for that DNS entry.
Asus Dual Wan Load Balance Problems Solving
The main issue I noticed when using Dual WAN in load balancing mode is occasionally slow page loading time, failing to load assets, switching between modems at inappropriate times or not loading at all. First rule is enough 2) I used different devices for testing the loadbalance. If you want to use the 2 WAN connections at the same you have to chose the option Load Balancing. Make sure to put correct data in the field Max Bandwidth provided by ISP. And for the Network Service Detection, whatever IP you chose make sure that it replies to ping and will not give false positive for WAN failure.
