notes/IT/RouterOS port forwarding.md

To port forward with RouterOS, you need allow the port through the firewall, and actually forward traffic

Allow through the firewall

1. Navigate to IP > Firewall from the sidebar, then go to the Filter Rules tab from the top
2. Select Add New to create a new rule
3. Set Dst. Address to the internal IP you want to allow traffic to
4. Set Protocol to 6 (tcp)
5. Set Dst. Port to the port you want to allow traffic through
6. Set In. Interface List to all (I'm sure this isn't the most correct option), but it works
7. Set Action to accept
8. (Optionally) add a comment explaining what you're doing
