Internal Closed Network External Access: Are You Still Port Forwarding?<\/h1>\n

Connect in 10 Seconds Without Port 443 Using Tailscale!<\/h2>\n

Hello! Today I’m introducing a cheat code that completely solves the ‘External Access’<\/strong> headache for Synology NAS users, company staff, and server operators.<\/p>\n

For security reasons, I used to worry about how to bypass SSH (22) or DB (5432) connections while only keeping port 443 open. My conclusion? ‘Tailscale’<\/strong> is the definitive answer.<\/p>\n

\ud83e\udd14 Why is Port Forwarding Dangerous?<\/h3>\n

Typically, to access internal devices like a NAS from the outside, you configure port forwarding on your router. While you can access a NAS via DSM, you can’t issue terminal commands. Moreover, port forwarding is akin to leaving your front door wide open to strangers. Leaving port 22 (SSH) or specific management ports open, in particular, exposes you to endless Brute Force hacking attempts.<\/p>\n

\ud83d\ude80 Tailscale: A Dedicated Virtual LAN Tunnel<\/h3>\n

Tailscale is a type of VPN, but the setup is almost absurdly simple. Without opening a single port (Zero Config), it connects to your NAS from anywhere in the world as if it were right next to you.<\/p>\n

—<\/p>\n

\ud83d\udee0\ufe0f 3-Minute Setup Guide<\/h3>\n

1. Install Tailscale on your Synology NAS (or any always-on device).<\/h4>\n

* Search for ‘Tailscale’ in the Synology Package Center<\/strong> and install it.
\n
\n* Launch the app and log in. You will be assigned your own unique IP (100.x.x.x<\/code>).<\/p>\n

2. Connect External Devices (Laptop\/Smartphone)<\/h4>\n

* Install Tailscale on your laptop and log in using the same account.
\n* Once you see ‘Connected’ in the Windows system tray, you’re all set!
\n* You’ll now be able to see devices connected to your internal network.
\n<\/p>\n

3. [Core Feature] Share Your Internal Subnet (Subnet Router)<\/h4>\n

As a DBA, wouldn’t you want to use your internal IP addresses (192.168.x.x<\/code>) natively? With just a single command via SSH on your Synology, you can access all devices on your home network (like your router’s admin page). This trick isn’t limited to Synology NAS, either!<\/p>\n

> [!tip] Execution Command (Requires root privileges)
> tailscale up --advertise-routes=192.168.x.0\/24 --netfilter-mode=off<\/code><\/p>\n

\ud83c\udf1f Real-World Review: What Changed?<\/h3>\n

– PuTTY Access<\/strong>: Say goodbye to port 443 mapping and complicated bypass configs. You can simply SSH into port 22 using your 100.x.x.x<\/code> address.
– Security<\/strong>: Zero ports are exposed to the outside web. Only devices authenticated with your account can establish a connection.
– Speed<\/strong>: Built on WireGuard, the connection is incredibly fast with no bottlenecks, even on an 8Gbps fiber connection.<\/p>\n

\ud83d\udca1 Wrapping Up<\/h3>\n

Say goodbye to the stress of complicated network configurations. Especially if you frequently handle n8n automation or external database management like I do, Tailscale<\/strong> isn’t just an option\u2014it’s a necessity.<\/p>\n

Go ahead and install it on your NAS and internal network today. You’re about to experience a whole new world!<\/p>\n","protected":false},"excerpt":{"rendered":"
