LABEL DESCRIPTION
General Settings
Enable Select this to enable VTI. Clear this to disable it.
Interface Properties
Interface Name This field is read-only if you are editing an existing VPN tunnel interface. For a new VPN
tunnel interface, enter the name of the VPN tunnel interface in vtix format, where x is a
number from 0 to the maximum number of VPN connections allowed for this model. For
example, enter vti10.
Zone Select a zone. Make sure that the zone you select does not have traffic blocked by a
security feature such as a security policy.
vpn-rule You should have created a VPN tunnel first for a VPN Tunnel Interface scenario. Select one
of the VPN Tunnel Interface scenario rules that you created.
IP Address
Assignment
IP Address Enter the IP address for this interface.
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.
Metric Enter the priority of the gateway (if any) on this interface. The Zyxel Device 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 Zyxel Device uses the one that was configured
first.
Enable IGMP Support Select this to allow the Zyxel Device to act as an IGMP proxy for hosts connected on the
IGMP downstream interface.
IGMP Upstream Enable IGMP Upstream on the interface which connects to a router running IGMP that is
closer to the multicast server.
IGMP Enable IGMP Downstream on the interface which connects to the multicast hosts.
Downstream
Interface Parameters
Egress Bandwidth Enter the maximum amount of traffic, in kilobits per second, the Zyxel Device can send
through the interface to the network. Allowed values are 0 - 1048576.
Ingress This is reserved for future use.
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the Zyxel Device can receive
from the network through the interface. Allowed values are 0 - 1048576.
Connectivity Check These fields appear when you select a vpn-rule.
The interface can regularly check the connection to the gateway you specified to make
sure it is still available. You specify how often the interface checks the connection, how long
to wait for a response before the attempt is a failure, and how many consecutive failures
are required before the Zyxel Device stops routing to the gateway. The Zyxel Device
resumes routing to the gateway the first time the gateway passes the connectivity check.
Enable Select this to turn on the connection check.
Connectivity
Check
Check Method Select the method that the gateway allows.
Select icmp to have the Zyxel Device regularly ping the gateway you specify to make sure
it is still available.
Select tcp to have the Zyxel Device regularly perform a TCP handshake with the gateway
you specify to make sure it is still available.
Check Period Enter the number of seconds between connection check attempts.
