Captive portal with load balancing

[jiggsfoo]

I just discovered from another post here that having a captive portal and load balancing is not possible.

What's the amount of work that is required to get this working? I'm not really into advanced networking but if someone can explain what the problem is, I might be able to help in some way.

Can someone give me an idea?

Thanks!
