3. (Optional) In the DHCP User Class (If Required) field, enter a host name.
If your ISP has given you a specific host name, enter it here. Otherwise, leave this field
blank.
4. (Optional) In the DHCP Domain Name (If Required) field, enter a domain name.
You can type the domain name of your IPv6 ISP. (Do not enter the domain name for the
IPv4 ISP here.) For example, if your ISP’
s mail server is mail.xxx.yyy
.zzz, type
xxx.yyy.zzz as the domain name.
If your ISP provided a specific domain name, type it in this field. (For example, Earthlink
Cable might require a host name of home, and Comcast sometimes supplies a domain
name.)
5. Specify how the modem router assigns IPv6 addresses to the devices on your home
network (the LAN) by selecting one of the following radio buttons:
• Use DHCP Server.
This method passes more information to LAN devices, but some
IPv6 systems might not support the DHCv6 client function.
• Auto Config
. This is the default setting.
6. (Optional) Select the
Use This Interface ID check box, and specify the interface ID that you
want to be used for the IPv6 address of the modem router’s
LAN interface.
If you do not specify an ID here, the modem router generates one automatically from its
MAC address.
7. Specify the IPv6 filtering mode by selecting one of the following radio buttons:
• Secured. In the secured mode, which is the default mode, the modem router inspects
both TCP and UDP packets.
• Open
. In the open mode, the modem router inspects UDP packets only.
8. Click the Apply
button.
Your settings are saved.
