18 CommPlete Communications Server
IP Address
Shows the IP network address for the RASExpress server’s Ethernet interface. It can
be edited only if IP Remote Access is enabled. The IP address must be assigned by
the system administrator, and it must be unique on the TCP/IP network.
IP Subnet Mask
Shows the IP subnet mask of the RASExpress server. This field can be edited only if
IP Remote Access is enabled. The mask shown in the example is the standard mask
for a Class C network (see page 7).
IP Default Route
Shows the IP address to which packets are sent that cannot be routed by the
RASExpress server. If there is no router on the network, the address should be filled
with zeroes. This field can be edited only if IP Remote Access is enabled.
IP RIP
Enables or disables the IP Routing Information Protocol (RIP-2). Enable IP RIP if you
want the RASExpress server to use RIP-2 for IP routing.
IP Auto Learn Default Gateway
Enables or disables RASExpress to learn the correct default gateway if you have
configured the default gateway incorrectly or if the configured gateway goes down
and a different router starts acting as a default router. This feature requires a RIP-2
router that supports default gateway broadcasting.
Primary Name Server
Shows the address of the primary name server that is used by the RASExpress server
to resolve names to IP addresses for Telnet and RLOGIN clients dialing in from a
dumb terminal. This field can be edited only if IP Remote Access is enabled.
Secondary Name Server
Shows the address of the secondary name server that is used by the RASExpress
server to resolve names to IP addresses for Telnet and RLOGIN clients dialing in
from a dumb terminal. The secondary name server is used when the primary name
server does not respond. This field can be edited only if IP Remote Access is enabled.
DNS Caching Server
Enable to have the RASExpress server act as a DNS server. When this option is
enabled, the RASExpress server gives out its IP address as the DNS server to dialing
PPP clients.
IP Frame Type
Shows the RASExpress server’s IP frame type. It can be edited only if IP Remote
Access is enabled. Two frame types are available: TYPE_II (the default) and SNAP.
Remote Client IP Address
Shows how the RASExpress server allocates IP addresses to remote client-to-LAN
users. Select Use DHCP if you have a DHCP server on your LAN. Select Use
Address Pool if the IP addresses you assign to the clients are mostly contiguous.
Select Configure Per Port (the default) if you want to assign a specific address to each
of the remote ports. For LAN-to-LAN ports you must configure all IP addresses
manually. Select Use Radius if you want to use your RADIUS server to assign IP
addresses.
