Tunnel

IPv6 address only works under IPv6 network environment. However, as the mainstream Internet structure is still under the IPv4 network environment, you need to enable IPv6 Tunnel for full Internet access. If you are not sure how to configure IPv6 or face any connection problems, please contact your Internet Service Provider.

To setup IPv6 Tunnel:

  1. Check the Enable tunnel checkbox to enable tunnel support.
  2. In Server address, enter the hostname or the IP of the tunnel service provider, for example: anonymous.freenet6.net.
  3. Select if you want to Connect anonymously or Connect with an existing account. If you choose the latter, please also enter User name and Password.
  4. Click OK to save the settings.

Note: Your external IPv6 address may be automatically updated by the service provider. However, Synology DiskStation will not remove the old IPv6 address immediately.
