We are load balancing 2 servers hosting an identical Craft environment.
When clicking around in the admin a user will get logged out after 30 seconds and sometimes even faster when browsing in the admin panel.
I am unable to set the load balancer to sticky sessions due to the load balancer sitting behind a Firewall which NAT's inbound traffic. So the load balancer see's all inbound traffic as a single IP.
Is there anything else that can be done to resolve this issue?
