If you run a small office on the Costa Blanca — a real estate agency, a law firm, a gestoría — chances are someone on your team occasionally needs to reach the office network from outside: checking a file from home, working from another branch, or handling something urgent while travelling.
The tempting shortcut is opening up remote desktop or file sharing directly to the internet "just for now." The problem is that "just for now" is exactly how offices end up compromised — exposed ports get found and probed within hours, not months.
Why WireGuard on MikroTik is the right way to do this
MikroTik routers are common in small Spanish offices because they're affordable and capable — but most are running with only the factory defaults, which don't include secure remote access. WireGuard is a modern VPN protocol that's fast, lightweight, and — importantly — considered one of the most secure and well-audited VPN protocols currently available.
Set up properly, it means:
- Anyone on the team can securely reach office files, printers or internal systems from home or on the road, as if they were sitting at their desk
- Nothing on the internal network is directly exposed to the internet — the only thing visible from outside is the encrypted VPN tunnel itself
- Access can be added or removed per device in minutes (someone leaves the company, their access is gone instantly)
Where this usually goes wrong when done alone
WireGuard itself isn't complicated once it's configured — but getting there involves a few steps that are easy to get wrong if it's not something you set up regularly:
- RouterOS package/version issues — WireGuard support depends on running a recent enough RouterOS version, and older MikroTik installs often aren't updated
- Key management — each device needs its own key pair; reusing keys or mixing them up is a common source of "it connects but nothing works" problems
- Routing and DNS — without correct routes and DNS settings, the tunnel connects but you still can't actually reach the office files or print server
- Firewall rules — the tunnel needs a narrow, correctly scoped firewall rule; too open defeats the purpose, too strict breaks it entirely
What we do
We configure WireGuard directly on your MikroTik router, generate and distribute the correct keys for each device or team member, set up routing so you can actually reach what you need once connected, and test the connection from an external network before handing it over — so it works the first time your team tries it, not after three rounds of troubleshooting.
If your team needs this
This is a one-time setup, not a recurring cost — once it's configured, it keeps working. It's included as part of our monthly IT support plans, or available as a standalone setup for offices that just need this one thing sorted properly.
