Hi,I have a TP Link TL-R470T+ load balancing router and I use it with an AirPort express. I always get a Double Nat error when I set the AirPort express to DHCP and NAT. Is there a way to turn off the DHCP service in the load balancer so that the issue will disappear? I've turned off DHCP server in the load balancer and that didn't seem to work. I need the setting on the AirPort Express to be set to "DHCP and NAT" as I need the guest network to be in a different subnet.

What do you mean" I've turned off DHCP server in the load balancer and that didn't seem to work"? The Clients still can get IPs from it?

Double NAT error has nothing to do with DHCP, but with separate, cascading subnets both using NAT. There are two ways to solve it: either set up one of the routers as a bridge (if possible at all) or use port forwarding to make services in the second subnet available to external sites. See also https://support.apple.com/en-us/HT203147 for a discussion of multiple-NAT configurations with Apple devices.
