•
DHCP Assumes Same Network
: specifies whether to try to reconnect to the
same DHCP assignment when the DCHP lease expires.
•
Local IP Address
: specifies the static IP address if Auto Local IP is disabled.
•
Network Mask
: specifies the network mask of the static IP address.
•
Gateway
: specifies the default gateway when static IP address is used.
•
Masquerade
: this enables network address translation for all LAN-originated
traffic leaving the oMG WAN interface. This is usually the preferred setting.
•
Automatic DNS
: if selected, the DNS servers provided by the network
service provider (via DHCP) will be used to resolve host names. This must be
disabled if using a static IP address.
If Automatic DNS is not selected, specific DNS server IP addresses can be
specified in the Primary DNS and Secondary DNS fields. All servers are con-
sidered as a group that optimizes DNS response time. The initial host name
resolution request is broadcast to all these servers and the one with the fast-
est response time is selected for future requests.
When a DNS resolution request times out, another broadcast is sent to all
DNS servers, and occasional DNS broadcasts are made to ensure the current
server is still the fastest.
Note: This forwarder optimization mechanism can create resolution issues when
VPNS are used in conjunction with internal DNS servers. This requires DNS zones to
be defined on the oMG—see
Configuring DNS Zones for Private DNS Server Use
page 43 for details.
•
Primary DNS
: specifies the IP address of the domain name server.
•
Secondary DNS Servers
: specifies the IP addresses of alternate domain
name servers.
•
Use Management Tunnel
: the management tunnel is an optional specialized
SSL VPN connection that is used only for two way communication between
the oMG and the AMM.
•
Pilot Ping
: enables or disables Pilot Ping. Disabled by default.
•
Monitors
: defines the monitor for detecting the availability of the link. The
factory-defined monitor is DefaultMonitor. This example should be replaced
with your own monitor definition.
•
Monitor Mode
: defines the action that will occur on the link if the monitor fails
or succeeds.
•
VPN
: select one or more of the defined VPNs. This is only applicable if VPNs
have been configured through VPN Configuration. Note that each of the
VPNs in a multi-VPN selection must be LAN to LAN.
•
Load Balanced
: When enabled, traffic can be allocated to multiple active
WAN links.
•
Weight
: used with the Load Balanced option to distribute traffic over the
various links. The system divides the value for Weight by the accumulated
total of Weight values assigned to all links, to determine the ratio around
which sessions will be distributed (e.g. if link A is assigned a value of 50 and
link B is assigned 100, then link A's ratio will be 50/150=33% and link B's ratio
will be 66%. In this scenario, link B will get twice as many sessions as link A).
