What must be configured on a router for remote access via Winbox?

To enable remote access to a router via Winbox, configuring firewall rules is essential. Firewalls serve as a security layer, controlling incoming and outgoing traffic based on predetermined security rules. Specifically, when accessing a MikroTik router using Winbox, the firewall must allow traffic on the ports that Winbox uses (typically port 8291). If appropriate rules are not configured, remote access attempts will be blocked, preventing successful connections to the router.

While settings like a public IP address, PPP connections, and DNS settings can be significant for general network connectivity or different types of access, they do not directly manage the security aspects necessary for remote access via Winbox. Without the correct firewall rules established to permit Winbox connections, any other configurations would not suffice to facilitate remote management of the router.
