Block all incoming traffic

RouterOS Beginner Basics
1

I want to block all incoming traffic to my network and allow all outgoing traffic from my network.
I tried this rule in miktotik’s firewall filter

chain=forward dst-address=xx.xx.xx.xx/28 connection-state=new action=drop

Where xx.xx.xx.xx/28 is our network addresses contains 16 Static IPs

This rule stops both incoming and outgoing connections. I want only incoming connections to be blocked not outgoing connections. e.g we have server running in xx.xx.xx.123:80 IP. Try to connect xx.xx.xx.123:80 from outside should not be connected.

Router: Mikrotik RB750 GL

Try input in place of forward

The Input chain is only for traffic which belongs to the router ( towards IP-addresses configured on some router interface ) not for traffic which is forwarded by the router
