LAN / Wireless LAN / Internet
DHCP is a network protocol for automatic IP configuration. To let DHCP assign an IP for the system, choose Get network configuration automatically (DHCP) and click Apply to save the setting.
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, keep the field blank.
Note:
- To make sure the email notifications are delivered correctly through the SMTP server, a valid DNS server IP should be entered.
- 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.
- Dynamic Host Configuration Protocol (DHCP) does not apply to wireless LAN.
- Internet configuration is available under Wireless Router mode.
- If you use DSL or cable modem to connect to the Internet via PPPoE (Point to Point Protocol over Ethernet), please go to the PPPoE tab for settings.
IPv6 Setup
Synology DiskStation supports IPv4/IPv6 dual stack scheme. This means that both IPv4 and IPv6 can work simultaneously on Synology DiskStation. The default settings for IPv6 is Auto. You can click the IPv6 Setup button under the LAN tab to change the settings.
In the IPv6 Setup page, choose between the different setup types:
- Auto: DiskStation will automatically generate a local IPv6 address. This is generated based on DiskStation's MAC address.
- DHCP: DiskStation will automatically get an IPv6 address from the DHCP server which supports IPv6.
- Manual: Set up IPv6 manually by entering IPv6 address, Prefix length, and Default gateway.
- Off: Disable IPv6 support.
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. This can be configured under the Tunnel tab.
