Synology-Bridging

This script enables you to create a network bridge between two Ethernet ports on your Synology NAS. As it works right now, it will connect ports 0-3 to port 4, but it should be easily customizable.

Don't

Using your NAS as a switch might work, but it might super not. For us it worked for a while, but every now and then it would just break. If you aren't really broke and need to save the 200$ for a switch, you probably should not do this.

Prerequisites

• DSM >= 6.1
• A Synology NAS with at least two Ethernet ports
• Administrator account on DSM
• Open vSwitch enabled

Instructions

• Upload the script to an arbitrary folder (preferably one that only Administrators can edit)

• Click the “Create” button on the top. Select “Triggered Task” → ”User-defined script”
• Type any title you wish and select the root user

• Move to “Task Setting” tab
• Type (or copy-paste) into the text box:

bash /path/to/vswitch_bridge

• Click the “OK” button
• Choose the “Enable Task” box
• Reboot (or run it once manually)
