IP DHCP Client = [ enabled I disabled]
The Dynamic Host Configuration Protocol (DHCP) allows users to setup a WAN port as client-only. In such
cases, a PPP client connected to this WAN port will be on the same IP network as the LAN port. This feature
can save some extra IP addresses that otherwise would have been taken up by the WAN port. Enabling this
option allows the RouteFinder to dynamically get an IP address for a PPP client coming up on one of its
"Client-only" WAN port. When this option is enabled, there must be a DHCP server or DHCP relay agent on
the connected LAN for the RouteFinder
to acquire an appropriate IP address.
This option applies only to the Client-only WAN port.
IP DHCP Relay Agent = [ enabled I disabled]
The RouteFinder is capable of relaying DHCP Packets across its port. In cases where these is no DHCP
server located on the LAN segment of the RouteFinder, this option needs to be enabled. The RouteFinder will
then relay the DHCP packets between clients on the directly connected networks and the server. Clients on a
directly connected network are clients on the LAN and a PPP client calling-in on a client-only WAN port.
DHCP Server IP Address = [ dotted decimal IP Address]
If an DHCP relay agent is enabled, the IP address of the DHCP server must be entered in this field.
DSN Resolver = [ enabled I disabled]
The RouteFinder supports Domain Name System (DNS) for the terminal server application. This is a built-in
telnet client which can connect a call coming in on a WAN port from a telnet host. When a user dials into the
system to get connected to a telnet server, the RouteFinder will prompt for a telnet host address. The user
can either type in the dotted decimal IP address or the domain name of the host.
Check this option if you are planning to use the DNS Resolver. If you disable this option, applications like
terminal server will not support domain names.
DNS Local Server Address = [ dotted decimal IP Address]
The IP address of the local DNS server is entered in this field.
DNS Root Server Address = [ dotted decimal IP Address]
The IP address of the local DNS server is entered in this field. This is used only if the local DNS server
doesn't respond.
IP Default TTL = [decimal value]
Defines the IP Time-To-Live parameter that sets the maximum number of hops a frame may travel before
being dropped. This is used to limit errant frames such as those that may arise under circularly defined
networks.
IP RIP Response Time = [decimal seconds]
Defines the time interval between periodic IP RIP broadcasts. Regular RIP broadcasts are required to keep
the routing tables of all routers in the internetwork consistent. Increasing the frequency of these broadcasts
may consume precious bandwidth that could have been used for transfer of other regular packets.
Recommended value: 30 seconds
IP Reassembly Timeout = [decimal seconds]
This value defines the amount of time the IP routing software will wait for all the fragments of an IP datagram
to arrive before discarding the partially reassembled datagram.
Recommended value: 30 seconds
IP RIP Route Aging Time = [decimal seconds]
Defines the time interval that must expire before an unused route entry created by IP RIP is aged from the
route table. The aging timer starts from the addition, reference, or change of an IP RIP based routed entry.
Recommended value: 180 seconds
