Chapter 7 Interfaces
Table 41 Configuration > Network > Interface > Ethernet > Edit (continued)
LABEL | DESCRIPTION | |
Subnet Mask | Enter the subnet mask of this interface in dot decimal notation. The subnet mask | |
| indicates what part of the IP address is the same for all computers in the network. | |
|
| |
Gateway | This option appears when Interface Type is external or general. Enter the IP | |
| address of the gateway. The ZyWALL sends packets to the gateway when it does not | |
| know how to route the packet to its destination. The gateway should be on the same | |
| network as the interface. | |
|
| |
Metric | This option appears when Interface Type is external or general. Enter the priority | |
| of the gateway (if any) on this interface. The ZyWALL decides which gateway to use | |
| based on this priority. The lower the number, the higher the priority. If two or more | |
| gateways have the same priority, the ZyWALL uses the one that was configured first. | |
|
| |
IPv6 Address | These IP address fields configure an IPv6 IP address on the interface itself. | |
Assignment |
| |
|
| |
Enable Stateless | Select this to enable IPv6 stateless | |
Address Auto- | will generate an IPv6 IP address itself from a prefix obtained from an IPv6 router in the | |
configuration | network. | |
(SLAAC) | ||
| ||
|
| |
This displays the IPv6 | ||
address | generates itself for the interface. | |
|
| |
IPv6 Address/ | Enter the IPv6 address and the prefix length for this interface if you want to use a | |
Prefix Length | static IP address. This field is optional. | |
| The prefix length indicates what the | |
| computers in the network, that is, the network address. | |
|
| |
Gateway | Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal | |
| notation. | |
|
| |
Metric | Enter the priority of the gateway (if any) on this interface. The ZyWALL decides which | |
| gateway to use based on this priority. The lower the number, the higher the priority. If | |
| two or more gateways have the same priority, the ZyWALL uses the one that was | |
| configured first. | |
|
| |
Address from | Use this table to have the ZyWALL obtain an IPv6 prefix from the ISP or a connected | |
DHCPv6 Prefix | uplink router for an internal network, such as the LAN or DMZ. You have to also enter a | |
Delegation | suffix address which is appended to the delegated prefix to form an address for this | |
| ||
| interface. See Prefix Delegation on page 107 for more information. | |
| To use prefix delegation, you must: | |
| • Create at least one DHCPv6 request object before configuring this table. | |
| • The external interface must be a DHCPv6 client. You must configure the DHCPv6 | |
| request options using a DHCPv6 request object with the type of | |
| • Assign the prefix delegation to an internal interface and enable router | |
| advertisement on that interface. | |

| |
Edit | Select an entry and click this to change the settings. | |
|
| |
Remove | Select an entry and click this to delete it from this table. | |
|
| |
# | This field is a sequential value, and it is not associated with any entry. | |
|
| |
Delegated | Select the DHCPv6 request object to use from the | |
Prefix |
| |
|
| |
Suffix | Enter the ending part of the IPv6 address, a slash (/), and the prefix length. The | |
Address | ZyWALL will append it to the delegated prefix. | |
| For example, you got a delegated prefix of 2003:1234:5678/48. You want to configure | |
| an IP address of 2003:1234:5678:1111::1/128 for this interface, then enter | |
| ::1111:0:0:0:1/128 in this field. | |
