Hi,
I wanted to change following NAT rule in my hotspot router:

4 D chain=hotspot action=redirect to-ports=64872 protocol=udp dst-port=53

Changing is not possible via Winbox, so I created a new rule and placed it before this rule:

1 chain=hotspot action=redirect to-ports=64872 protocol=udp hotspot=!auth dst-port=53

Then I deleted the original rule. Unfortunately after a reboot the rule reappears.
Any idea how to overcome this issue?
Thx in advance
Richard
