Can not block port through loadbalacing gateway

[hoangle]

Hi all,
I have problem when define this rule below

When I applied this rule, LAN net can not access internet. So now I have to bypass any/any.
(Loadbalance gateway use two interfaces)

So I prefer block all port and bypass some specific port(80,443,22....)But I cannot, so anyone can help me for this issue

You need to allow DNS on UDP port 53 to the LAN address at a minimum for clients to be able to browse the web.
