Hi

I have this local network
and please tell me how can remove the nat for access point and using only router nat ?

My router is: rb1100ahx2
My accesses point is: wAP ac (RBwAPG-5HacT2HnD )

There are a number of ways you can do this. You could setup dhcp on your main router and then bridge your lan port on your AP's to your wireless. Number 2 setup static routes for each lan behind the wireless on the main router and then remove nat. This would require you to change the lan address behind one of your AP's as they cannot be the same or your would have to split those subnets into a /25

Use static routing and route all traffic to your main router and do the nat there.

Thanks very much. I set the routes and everything works perfect.
