IP Address
Obtain an IP
Address
Automatically
Select this option if your ISP did not assign you a fixed IP address. This is the default
selection.
Static IP Address Select this option if the ISP assigned a fixed IP address.
IP Address Enter your WAN IP address in this field if you selected Static IP Address.
Subnet Mask Enter the Subnet Mask in this field.
Gateway IP
Address
Enter a Gateway IP Address (if your ISP gave you one) in this field.
MTU Size Enter the MTU (Maximum Transmission Unit) size for each packet. If a larger packet
arrives, the EMG2926-Q10A divides it into smaller fragments.
DHCP Option
Enable DHCP Option
121
Select this to enable the classless route option 121.
Enable DHCP Option
125
Select this to add vendor specific information to DHCP requests that the EMG2926-
Q10A sends to a DHCP server when getting a WAN IP address.
Enable DHCP Option
60
Select this to identify the vendor and functionality of the EMG2926-Q10A in DHCP
requests that the EMG2926-Q10A sends to a DHCP server when getting a WAN IP
address.
Vendor ID Enter the Vendor Class Identifier (Option 60), such as the type of hardware or
firmware.
6RD
Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When
the EMG2926-Q10A has an IPv4 WAN address and you set IPv6/IPv4 mode to IPv4 Only, you can enable 6rd
to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The EMG2926-Q10A generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the
ISP’s Border Relay router to connect to the native IPv6 Internet. The local network can also use IPv4 services.
The EMG2926-Q10A uses its configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.
This is available only when you select IPv4 Only in the IPv6/IPv4 field.
Enable 6RD Enable IPv6 rapid deployment to tunnel IPv6 traffic from the local network through the
ISP’s IPv4 network.
Automatically
configured by DHCP
Select this to have the EMG2926-Q10A detect the relay server’s IP address
automatically through DHCP.
Manually Configured Select this if you have the IPv4 address of the relay server.
Border Relay IPv4

Specify the relay server’s IPv4 address.
Service Provider
IPv6 Prefix
Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP’s Border Relay router and
connecting to the native IPv6 Internet.
Service Provider
IPv6 Prefix length
Enter the IPv6 prefix length.
An IPv6 prefix length specifies how many most significant bits (starting from the left) in
the address compose the network address.
IPv4 mask length Enter the subnet mask number (1~32) for the IPv4 network.
