LAN/Internet

Depending on your DiskStation model and network settings, you can configure DHCP settings for LAN or Internet at Control Panel > Network > Network Interface. DHCP is a network protocol for automatic IP configuration. To let DHCP assign an IP for the system, click Edit and choose Get network configuration automatically (DHCP) under the IPv4 tab.

If you are using a specific IP address from your network service provider, choose Use manual configuration and manually enter the IP address and subnet mask. If a DNS server or a default gateway is not available, leave the field blank.

Note:

  1. To make sure the email notifications are delivered correctly through the SMTP server, a valid DNS server IP should be entered.
  2. Jumbo Frames are Ethernet frames with more than the standard 1500 bytes of Maximum Transmission Unit (MTU), allowing Ethernet transmission of large files to be more efficient. It can only be enabled under Gigabit network environment. To ensure Jumbo Frame works properly, all the computers and devices across the network accessing your DiskStation must support it and use the same MTU value.

VLAN

When the network environment requires VLAN settings, you can enable the VLAN option and enter a VLAN ID for the network environment under the IPv4 tab in the Edit window.

Note:

IPv6 Setup

DiskStation devices support IPv4/IPv6 dual stack schemes. This means that both IPv4 and IPv6 can work simultaneously on your DiskStation. The default settings for IPv6 is Auto. Select an existing network interface, click the Edit button, and go to the IPv6 tab to change settings.

To configure IPv6 settings:

  1. Go to Control Panel > Network > Network Interface.
  2. Select an existing network interface and click Edit.
  3. Under the IPv6 tab, select a setup type from IPv6 setup:

Until IPv6 completely supplants IPv4, IPv6 transition mechanisms are needed to enable hosts with IPv4 addresses to reach IPv6 services. Choose among the different IPv6 transition mechanisms:

802.1X

802.1X is an authentication standard developed by the IEEE for user connection networks. 802.1X can be used in networks to authenticate the client, not allowing clients that have not successfully passed authentication to access the protected network.

You can allow your Synology NAS to connect to the network protected by 802.1X authentication.

To enable 802.1X authentication:

  1. Go to Control Panel > Network > Network Interface.
  2. Select a wired network interface (i.e. LAN) and click Edit.
  3. Go to 802.1X tab and check Enable 802.1X authentication.
  4. Select one of the following protocols from the Authentication drop down menu. If you are unsure which protocol is the most suitable, select Auto.     
  5. If you choose TTLS or PEAP, you select one of the inner authentication protocols from the drop down menu.
  6. Enter your username and password.
  7. If required, click Import, then Browse to find and import a certificate exported from Radius server (For example ca.crt).
  8. Click OK to save your settings.

Note:

Wireless LAN*

When your DiskStation acts as a wireless router, you can configure the following Wireless LAN settings at Control Panel > Network > Network Interface.

IPv4 Settings

IP Address and Subnet Mask

You can set the IP address and subnet mask for your DiskStation here.

DHCP Server

Check the option Enable DHCP server to allow your DiskStation to assign IP addresses to client devices that connect to the local network provided by your DiskStation.

PPPoE Relay

Enable PPPoE Relay to allow devices that are connected to your DiskStation to connect to the Internet via PPPoE connection.

Configure as UPnP Internet Gateway

Enable UPnP service to allow your DiskStation to become a UPnP Internet Gateway device, so that devices that are connected to the local network of your DiskStation can configure port forwarding settings with UPnP.

IPv6 Settings

You can get an IPv6 address and prefix from LAN/Internet with 6in4, 6to4, or DHCP-PD. With this information, you can configure IPv6 routing options for your DiskStation here.

There are three Router Advertisement (RA) modes to select from:

DHCP Clients

Here you can view a list of DHCP clients and their network configurations (e.g., MAC address, IP address, hostname, and the amount of time left before the DHCP lease expires).

You can filter the IPv4/IPv6 client drop-down list to show clients who are using IPv4 and IPv6, respectively. Choose a client and click Add to address reservation to add the client to the address reservation list.

DHCP Reservation

If you want a client to always receive the same IP address during DHCP lease renewal, you can add the client to the address reservation list.

You can filter the IPv4/IPv6 address reservation drop-down list. The IPv4 addresses are identified by MAC address, whereas IPv6 addresses are identified by DUID.

To add a client to the address reservation list:
