Why do some providers block certain features?

Have you ever tried to open a port, use your own router, or host a service… and it just doesn’t work? In many cases, the problem doesn’t come from your setup… but from your provider.

In Switzerland, some providers deliberately limit certain features. But why?

---

1. CGNAT: the invisible block

Many providers use what is called CGNAT (Carrier-Grade NAT).

In practice:

• You do not have a real public IP address
• You are behind a “large shared router” with other customers

Result:

• Impossible to open ports
• Remote access is complicated (NAS, cameras, server…)
• Problems with certain games or VPNs

👉 And often… this is not even clearly explained to the customer

---

2. Forcing the sale of options

Some limitations are simply… commercial.

Examples:

• Fixed IP only as a paid option
• Ports blocked by default
• Advanced features reserved for “pro” plans

👉 Goal: push you to pay more to unlock something basic

---

3. Locked routers

Some providers impose their own router with restrictions:

• Impossible to change certain settings
• Bridge mode missing or limited
• Restricted admin access

👉 Result: you don’t actually control your own connection

---

4. Security as a pretext

Officially, providers often cite security:

• Blocking certain ports
• Limiting incoming connections
• Preventing certain configurations

This is partially true… but also a simple way to reduce support requests.

5. Network simplification

Fewer options means fewer problems to manage.

By limiting features:

• Fewer support tickets
• Less technical complexity
• More standardised infrastructure

👉 But at the expense of advanced users…

---

6. Lack of transparency

The real problem is not always the limitation itself… it’s that it is often hidden or poorly explained.

Many customers only discover the restrictions when:

• They want to install a NAS
• They set up a VPN
• They move to advanced remote working

---

Is this normal?

A provider can make technical choices. But the customer should always know:

• Whether they have a real public IP
• What they can or cannot do
• What the actual limitations are

Our vision at MaxiConnect

At MaxiConnect, we make a simple choice:

• No unnecessary blocking
• Full access to your connection
• Fixed IP available for everyone (including private customers)

Conclusion

If certain features don’t work for you, it’s not always a bug…

👉 It’s often a deliberate limitation by your provider.

Before choosing a plan, ask yourself the right questions:

• Do I have a real public IP?
• Can I open ports?
• Can I use my own equipment?

Because in the end, an Internet connection should give you freedom… not restrictions.
