Figure 5-19: Routing and Gateways
To configure Routing and Gateways:
1. In Default Router, select Gateway and enter the IP address in the Gateway field.
2. In the Device field, select the required interface from the drop-down menu.
3. Configure Static routes or Local routes as required, or leave as is to enable the
default routing and gateway configuration.
Static routes – configured to enable traffic to choose another route to some known host
or network, rather than going through the default route.
Local routes – set up routing to additional IP networks on connected LANs
4. Click Save.
2.5.3 DNS Client
Clicking DNS Client in the Advance Network Settings screen, displays the DNS Client
screen. DNS Cache enables caching of Domain names and addresses which reduces network
traffic to and from the DNS Server and hence speeds up system performance.
The following behavior is supported by the DNS Cache mechanism. It performs a DNS health
check which is carried out on all configured DNS servers through the DNS protocol. If there is
a DNS failure, then there is automatic failover between servers. The DNS cache is persistent
which means that it can survive an appliance reboot. Caching is enabled also for multi-IP hosts
if they are provided by the configured DNS Servers through the DNS Protocol.
When the DNS cache is enabled and the user changes the DNS servers settings there is no need
to run restart role.
