IP/DNS
The Domain Name Server parameters used by the Router Option
Module are specified here. The DNS server addresses can be ex-
changed between PPP peers. When a connection occurs and IPCP is
negotiated, the Router Option Module will get the DNS server ad-
dresses from the PPP peer.
If the configured DNS server addresses (Server 1 and Server 2) are
all zeros, the addresses from the PPP peer are used. In NAT mode,
the PPP peer’s DNS addresses are always used. The DNS addresses set
in Server 1 and Server 2 are offered to a PPP peer, if so requested.
DNS/Domain Name
Write security: 3; Read security: 5
This is a text string used to represent the domain name used by the
Router Option Module.
DNS/Server 1
Write security: 3; Read security: 5
This is the IP address for the primary DNS device. It is the first serv-
er to which domain name requests are sent.
DNS/Server 2
Write security: 3; Read security: 5
This is the IP address for the secondary DNS device. It is used as a
back-up in case the primary address does not respond to the re-
quest.
IP/UDP Relay
The Router Option Module can be configured as a relay agent for
UDP broadcast packets. Normally, a router will not forward UDP
broadcast packets. However, many network applications use UDP
broadcasts to configure addresses, host names, and other informa-
tion. If hosts using these protocols are not on the same network seg-
ment as the servers providing the information, the client programs
will not receive a response without enabling the UDP relay agent.
UDP Relay/Mode
Write security: 3; Read security: 5
When this option is set to On (def), the Router Option Module will
act as a relay agent.
