Configuring network protocol parameters
Using the PPP Incoming Connection Wizard,
you can enter the following information to define how the IP
network protocol will be configured for the PPP link:
Local address assigned by-
Select Remote if the remote user assigns the IP
address of your end of the link each time it is established.
Select Local if the IP address for your end of the
PPP link is defined locally.
Local IP address/host name-
The IP address of the local end of the PPP link or
a host name that is resolvable to an IP address.
Remote address assigned by-
Select Remote if the remote user assigns the IP
address of the remote end of the link each time it is established.
Select Local if the IP address for the
service provider's end of the
PPP link is defined locally.
Remote IP address/host name-
The IP address of the remote end of the PPP link or
a host name that is resolvable to an IP address.
WARNING:
Do not assign the same remote address to different incoming users if it
is possible for them to be accessing the remote access server at the
same time. If necessary, you can use the PPP Manager
to configure an incoming bundle to use dynamically assigned
IP addresses obtained from a pool of IP
addresses maintained by the Address Allocation Server.
You can configure dynamic IP address assignment via the
IP Protocol
button in the incoming bundle's
``Network protocol options''.
Use as default route-
Select Yes if a default route to outside networks should
be established in the routing table via the new PPP interface
when the link is brought up. The route will also be deleted when the link is
taken down again.
Select No if the local host already has a network interface and
you do not want this to stop being the default route.
NOTE:
A remote access server will typically be configured as the
gateway to local networks or the Internet.
For this reason, this option should usually be set to No.
Local host acts as gateway-
Select Yes if the host at your end of the PPP
link will act as a router for packets between the local network and the
remote end of the link.
Select No if you do not want the local machine to act as a router
or it is not connected to a local network.
NOTE:
A remote access server will typically be configured as the
gateway to local networks or the Internet.
For this reason, this option should usually be set to Yes.
Act as proxy for ARP-
Select Yes if the remote access server
will act as a proxy for Address Resolution Protocol (ARP)
requests on local networks on behalf of the host at
the remote end of the link.
This is necessary if the IP address and network mask of the
remote end of the link defines it to be on a local network to which the
remote access server is directly connected.
Because the PPP interface of the machine at the remote end
of the link does not have a hardware (MAC) address,
it cannot answer ARP
requests for this address from machines on the local network.
The proxy machine must instead answer
all ARP requests on behalf of the
remote machine with its own MAC address.
It examines the destination IP address of all network
packets that are sent to its MAC address. If a packet's
destination IP address is that of the machine at the
remote end of a PPP link, it
forwards the packet on the appropriate PPP interface.
Select No if the IP address and network mask
of the host at the remote end of the link defines it as not being
on a local network.
