Keep your ports closed and connect to your internal network through a secure Client VPN tunnel instead.
Client VPN gives you secure, encrypted access to your LAN without exposing anything to the internet.
It keeps your systems protected behind the firewall where they belong.
Setup Guides:
Instant Exposure:
The moment you open a port, your service is indexed by scanners like Shodan.io—often within hours.
Your public IP:port combination becomes a permanent target for automated attacks.
You’re effectively removing your firewall’s protection and relying entirely on the app’s own security.
Real-World Risk:
Firewall Threat Analysis can only block some HTTP or HTTPS threats—it doesn’t cover all protocols or new exploits.
Any new vulnerability (a “zero-day”) in that exposed service can be exploited instantly.
You’re betting your network’s safety on the software developer keeping up with global attackers.
Proceed with extreme caution and follow these steps:
Required Protections:
In the Portal > Firewall > port forwarding settings, choose “Accept traffic exclusively from certain sources.”
Add only the specific IP addresses that truly need access.
Review and update this list often.
Monitor system logs regularly for suspicious activity.
Apply software updates immediately when available.
Know the Limits:
IP restrictions do not protect you from attacks if one of those allowed systems is compromised.
Threat Analysis provides only basic HTTP protection.
Any flaw in the exposed software gives attackers a direct entry point into your network.
Once you open a port, it will be attacked—constantly.
No matter how careful you are, eventually a vulnerability will appear, and it will be exploited.
Using a Client VPN eliminates that exposure completely.
Your services stay hidden from the internet, yet fully accessible to you and your team through a secure, authenticated connection.
