Blocking all access except VPN traffic on specfic ports

RouterOS Beginner Basics

Hi guys,

I am totally new to Microtek and am learning. So far, thanks to various forums and plenty of reading, I have setup a site to site VPN among two sites using OpenVPN.

What I would like to do next that I am having hard time dealing with:

Remote network 192.168.0.X / Local Network 192.168.100.X

remote router 192.168.0.1 / local router 192.168.100.1

remote PC 192.168.0.10 / Local PC 192.168.100.10

I want to allow port 9000 / 9020 to flow to the site to site VPN tunnel and that’s it.

All other traffic to drop. No matter if its external DNS , Web Surfing, Just would like those two ports to flow through. Once I get this working, I will add Winbox for remote management.

Can someone please lend me a hand ?

thanks
