Some of my apps verify that the ip address is allowed to access the app… but this isn’t working because all requests are going through the load balancer and the cgi.remote_host (what i currently use to verify a users ip) is always going to show the load balancer.  How do I work around this issue?

AFAIK, don't think there's much to do about it except create a "proper" user authentication scheme using a login and password. IP solutions are dodgy at best and as you are seeing can all sorts of unforseen issues. Plus services like AOL route all traffic through a few IPs in Virginia and anyone with a dynamic address (dialup) would be SOL. Maybe that's not an issue for your app but it does show the weakness of IP authentication.

So SideFishes, there is no way to get the clients ip instead of the load balancers ip?

afaik, not in CF. From what I've read some load balancers can be set up to modify http headers with http-proxy information and some can be set to "transparent" mode...but this really is dependant on what you are using for LB (and is certainly beyond me)
