In some cases you may want to connect your Synology NAS to multiple vlans. You may have different network cards, but why would you like to give away the advantage of loadbalancing/failover of an aggregated link, right? It is not possible using web interface, but it is fairly easy.
Create LACP Bond device and configure you network as usual. Please make use you check
Enable VLAN (802.1Q)
Then login into Synology using
ssh and change the directory to
In this directory you find config for your network interfaces. Names of this configs looks like
ifcfg-bond0.40. From first part
ifcfg Synology knows, thas it is netwrok config file, second part
bond0 is the name of vlan and last part
.40 is VLAN id. So if you want to create new vlan interface, just copy this file, rename it and change VLAN ID in config:
example of config file:
Make sure that you set the
VLAN_ID appropriately to the match VLAN. To activate the new bond interface just restart Synology NAS.
After restart you should see new network interface in web interface:
If you for some reason can’t connect to Synology NAS after restart, just reset network and start over. Don’t worry, your files and apps stay untouched.
