Chapter 8 Interfaces Table 46 Configuration > Network > Interface > VLAN > Edit (continued) LABEL Connectivity Check Enable Connectivity Check Check Method DESCRIPTION The UAG can regularly check the connection to the gateway you specified to make sure it is still available. You specify how often to check the connection, how long to wait for a response before the attempt is a failure, and how many consecutive failures are required before the UAG stops routing to the gateway. The UAG 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 UAG regularly ping the gateway you specify to make sure it is still available. Check Period Check Timeout Check Fail Tolerance Check Default Gateway Check this address Check Port DHCP Setting DHCP Select tcp to have the UAG 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 UAG 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. The DHCP settings are available for the OPT, LAN and DMZ interfaces. Select what type of DHCP service the UAG provides to the network. Choices are: None - the UAG does not provide any DHCP services. There is already a DHCP server on the network. DHCP Relay - the UAG routes DHCP requests to one or more DHCP servers you specify. The DHCP server(s) may be on another network. Relay Server 1 Relay Server 2 IP Pool Start Address DHCP Server - the UAG assigns IP addresses and provides subnet mask, gateway, and DNS server information to the network. The UAG is the DHCP server for the network. These fields appear if the UAG 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 UAG is a DHCP Server. Enter the IP address from which the UAG begins allocating IP addresses. If you want to assign a static IP address to a specific computer, click Add Static DHCP. Pool Size If this field is blank, the Pool Size must also be blank. In this case, the UAG 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. Enter the number of IP addresses to allocate. This number must be at least one and is limited by the interface's Subnet Mask. For example, if the Subnet Mask is 255.255.255.0 and IP Pool Start Address is 10.10.10.10, the UAG can allocate 10.10.10.10 to 10.10.10.254, or 245 IP addresses. If this field is blank, the IP Pool Start Address must also be blank. In this case, the UAG 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. 126 UAG715 User's Guide

Connectivity Check
The UAG can regularly check the connection to the gateway you specified to make sure
it is still available. You specify how often to check the connection, how long to wait for a
response before the attempt is a failure, and how many consecutive failures are
required before the UAG stops routing to the gateway. The UAG resumes routing to the
gateway the first time the gateway passes the connectivity check.
Enable
Connectivity
Check
Select this to turn on the connection check.
Check Method
Select the method that the gateway allows.
Select
icmp
to have the UAG regularly ping the gateway you specify to make sure it is
still available.
Select
tcp
to have the UAG 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.
Check Timeout
Enter the number of seconds to wait for a response before the attempt is a failure.
Check Fail
Tolerance
Enter the number of consecutive failures before the UAG stops routing through the
gateway.
Check Default
Gateway
Select this to use the default gateway for the connectivity check.
Check this
address
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.
Check Port
This field only displays when you set the
Check Method
to
tcp
. Specify the port
number to use for a TCP connectivity check.
DHCP Setting
The DHCP settings are available for the OPT, LAN and DMZ interfaces.
DHCP
Select what type of DHCP service the UAG provides to the network. Choices are:
None
- the UAG does not provide any DHCP services. There is already a DHCP server
on the network.
DHCP Relay
- the UAG routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP Server
- the UAG assigns IP addresses and provides subnet mask, gateway, and
DNS server information to the network. The UAG is the DHCP server for the network.
These fields appear if the UAG is a
DHCP Relay
.
Relay Server 1
Enter the IP address of a DHCP server for the network.
Relay Server 2
This field is optional. Enter the IP address of another DHCP server for the network.
These fields appear if the UAG is a
DHCP Server
.
IP Pool Start
Address
Enter the IP address from which the UAG begins allocating IP addresses. If you want to
assign a static IP address to a specific computer, click
Add Static DHCP
.
If this field is blank, the
Pool Size
must also be blank. In this case, the UAG 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.
Pool Size
Enter the number of IP addresses to allocate. This number must be at least one and is
limited by the interface’s
Subnet Mask
. For example, if the
Subnet Mask
is
255.255.255.0 and
IP Pool Start Address
is 10.10.10.10, the UAG can allocate
10.10.10.10 to 10.10.10.254, or 245 IP addresses.
If this field is blank, the
IP Pool Start Address
must also be blank. In this case, the
UAG 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.
