Small firewall question

RouterOS Beginner Basics
1

Hi,

I want to put a small MikroTik device inbetween a home ISP router and one specific PC. So port 1 goes to the existing router, and port 2 goes to the PC.

The point is to block certain traffic. I want to for instance only allow TCP port 80 and 443 (+DHCP and DNS of course) from that PC.

Can someone point me in the right direction?

Thanks!

You will have to use the bridge.
Then either use bridge filters, or enable “Use IP firewall” for bridge, and use firewalling to block it.

In firewall, simply drop everything other than what you want to allow.
