Configuring network interfaces
Use mask a.b.c.d for this interface
The default value in this text box will normally work, and should only be changed if it is known
that the default is not appropriate. Since PPP is a peer-to-peer protocol, this value is
appropriate in most situations.
Use the following DNS servers if not negotiated
Sets primary and DNS servers to use if a DNS server is not assigned as part of the PPP
negotiation and connection process.
Primary DNS server
The IP address of the primary DNS server to use if a DNS server is not assigned as part of the
PPP negotiation and connection process. It is fairly common practice for the DNS server to be
assigned automatically by the ISP when making a connection.
Secondary DNS server
The IP address of the secondary DNS server to use if one is not automatically assigned by the
remote peer.
DNS Port
The network port number of the DNS server.
Attempt to assign the following IP configuration to remote devices
When enabled, displays following four configuration parameters, which control how the PPP
instance assigns an IP address to a connecting remote peer. The primary and secondary DNS
server addresses will also be sent to the remote peer
Assign remote IP addresses from a.b.c.d to a.b.c.d
The IP addresses in these text boxes define the pool of IP addresses to assign to remote peers
during the IP protocol configuration phase of the PPP negotiation process.
Primary DNS server
The IP address of the primary DNS server that the remote peer should use when making DNS
requests over the link.
