IBR350
EXAMPLE: If you want to associate this rule with your guest LAN, you could input the IP address and netmask for
the guest LAN here (leaving the last slot "0" to allow for any user attached to the guest network):
•
Source IP Address: 192.168.10.0
•
Source Netmask: 255.255.255.0
Application Set: Application sets can be defined in the Application Sets tab of the Firewall Configuration
page. The application identification might not take place until multiple packets have already bypassed a rule.
Application sets require an active license to exist on the device for them to function.
DSCP (DiffServ): Differentiated Services Code Point (DSCP) is the successor to TOS (Type of Service). Use
this field to select traffic based on the DSCP header in each IP packet. This field is sometimes set by latency
sensitive equipment such as VoIP phones. This setting is optional.
DSCP Negate: When checked this rule will match on any packet that does not match the DSCP field.
Click Finish to save this rule.
DNS SERVERS
DNS, or Domain Name System, is a naming system that translates between domain names (www.cradlepoint.
com, for example) and Internet IP addresses (206.207.82.197). A DNS server acts as an Internet phone book,
translating between names that make sense to people and the more complex numerical identifiers. The DNS
page for the device has these distinct functions:
•
DNS Settings: By default your router is set to automatically acquire DNS servers through your Internet
provider (Automatic). DNS Settings allows you to specify DNS servers of your choosing instead (Static).
•
Split DNS: Enable or disable the redirecting of specified domains to alternate DNS servers.
•
Dynamic DNS Configuration: Allows you to host a server (Web, FTP, etc.) using a domain name that you
have purchased (www.example.com) with your dynamically assigned IP address.
•
Known Hosts Configuration: Allows you to map a name (printer, scanner, laptop, etc.) to an IP address of a
device on the network.
DNS Settings
You have the option to choose specific DNS servers
for your network instead of using the DNS servers
assigned by your Internet provider. The default DNS
servers are usually adequate. You may want to assign
DNS servers if the default DNS servers are performing
poorly or if you have a local DNS server on your
network.
Mode: Automatic or Static (default: Automatic).
Switching to "Static" enables you to set specific DNS
servers in the Primary DNS and Secondary DNS fields.
Primary DNS and Secondary DNS: If you choose to specify your DNS servers, then enter the IP addresses of the
servers you want as your primary and secondary DNS servers in these fields. The DNS server settings will be
pre-populated with public DNS server IP addresses. You can override the IP address with any other DNS server
IP address of your choice. For example, Google Public DNS servers have the IP addresses 8.8.8.8 and 8.8.4.4
while 4.2.2.2 and 4.2.2.3 are servers from Level 3 Communications.
