Is It Safe to Forward Ports to My Server?

Forwarding a port is routine — every public-facing server does it, including the one serving this page. The real question is what you're forwarding it to, and whether that thing is ready to be reachable from the internet.

The tunnel itself is encrypted

Traffic between our edge and your server travels over an encrypted connection — the same category of technology used by corporate VPNs. Nobody sitting between our network and yours can read or tamper with it. That part's handled for you.

What becomes your responsibility once you're exposed

Once a port is reachable from the internet, so is whatever's listening on it. A few habits matter more than anything else:

• Keep exposed software updated. An outdated SSH, game server, or web app version is the single most common way an exposed service gets compromised — not some exotic attack, just a known bug nobody patched.
• Don't forward things that assume they're private. A database port, an admin panel without its own authentication, an RDP port with a weak password — these are built with the assumption that only trusted machines can reach them. Forwarding them to the internet removes that assumption without adding protection back.
• Use strong, unique credentials on anything reachable this way, same as you would for any other public-facing account.

What we check, so one customer can't expose another

On shared (port forwarding) plans, your rules are checked against every other customer's rules on the same IP before they're ever activated — overlapping ports are rejected outright, so there's no scenario where one customer's forwarding rule accidentally exposes or collides with someone else's traffic.

A reasonable default

If you're not sure whether something should be exposed, ask: "would I be comfortable with this reachable from anywhere on the internet, today, as currently configured?" If the honest answer is no, fix that first — a tunnel gets traffic to your server; everything after that is the same security hygiene any internet-facing service needs.
