ZyWALL USG 300 User's Guide
DESCRIPTION
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 ZyWALL stops routing to
the gateway. The ZyWALL resumes routing to the gateway the first time the
gateway passes the connectivity check.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the ZyWALL regularly ping the gateway you specify to
make sure it is still available.
Select tcp to have the ZyWALL regularly perform a TCP handshake with the
gateway you specify to make sure it is still available.
Enter the number of seconds between connection check attempts.
Enter the number of seconds to wait for a response before the attempt is a
failure.
Enter the number of consecutive failures before the ZyWALL stops routing
through the gateway.
Select this to use the default gateway for the connectivity check.
Select this to specify a domain name or IP address for the connectivity check.
Enter that domain name or IP address in the field next to it.
This field only displays when you set the Check Method to tcp. Specify the port
number to use for a TCP connectivity check.
Select what type of DHCP service the ZyWALL provides to the network.
Choices are:
None - the ZyWALL does not provide any DHCP services. There is already a
DHCP server on the network.
DHCP Relay - the ZyWALL routes DHCP requests to one or more DHCP
servers you specify. The DHCP server(s) may be on another network.
DHCP Server - the ZyWALL assigns IP addresses and provides subnet mask,
gateway, and DNS server information to the network. The ZyWALL is the DHCP
server for the network.
These fields appear if the ZyWALL is a DHCP Relay.
Enter the IP address of a DHCP server for the network.
This field is optional. Enter the IP address of another DHCP server for the
network.
These fields appear if the ZyWALL is a DHCP Server.
Enter the IP address from which the ZyWALL begins allocating IP addresses. If
you want to assign a static IP address to a specific computer, click Edit static
DHCP table.
If this field is blank, the Pool Size must also be blank. In this case, the ZyWALL
can assign every IP address allowed by the interface's IP address and subnet
mask, except for the first address (network address), last address (broadcast
address) and the interface's IP address.
