MikroTik is not the problem, bad configuration is

MikroTik can run extremely stable, but business configuration must be readable. If nobody knows why a NAT rule exists, who uses a VPN account or which port is exposed to the internet, risk grows.

The first task is not adding one more rule, but reviewing the current state and removing what no longer has a purpose.

  • Firewall filter rules
  • NAT and port forwards
  • VPN users and profiles
  • DHCP, DNS and static addresses
  • Configuration backup and export

Firewall rules that can be understood

Firewall rules should be grouped by purpose: inbound traffic, local zones, VPN, administration, blocks and exceptions. Every rule needs a comment because after six months nobody remembers why it was added.

Good practice is to avoid exposing router administration to the internet, restrict sources and publish services only when there is a real need.

VPN for accounting, remote workers and branch locations

VPN is not only about letting someone connect. You need to define who needs access, to which server, through which ports and from which group. Accounting access is not the same as a site-to-site link between locations.

When VPN is properly separated, an incident or compromised account does not open the entire network.

How we take over a MikroTik environment

We first create backup, export and read the configuration. Then we label rules, look for unnecessary exposed services, check VPN and prepare a clean-up proposal without interrupting operations.

Only after that do we change configuration, in an agreed window and with a quick rollback option.
