HotSpot Problem

Hey all,
I’m running MikroTik v5.11 on RB433+R52 and trying to setup hotspot and NAT on the same machine .
It works good ,but when WAN port disabled/cable unplugged or ISP does not work, does not work and login page :frowning: .
I tried version 5.9 ,5.7 ,5.5 and 2.9.35 on RB133 ,the same problem.
Can someone help me?
