DHCP Address
Pool Start and
Pool End
If the InterProxy needs to support DHCP (Dynamic Host Configuration Protocol) for
client computers, select and enter the pool of DHCP addresses available on the
InterProxy.
Note: If you do not specify a DHCP address range, then all “guest” PCs must be
configured with static IP addresses.
DHCP IP addresses must meet the following requirements:
• The DHCP address group must fall within the port's IP address pool. The
available IP address pool is based both on the IP address and the subnet mask
configured for the port.
• The host IP address and the broadcast IP address cannot be within the DHCP
address pool.
• The DHCP range cannot overlap any other equipment (Ethernet switches or
CO/CPE modems)
Given an ETH 1 IP address of 10.237.1.1 and network mask of 255.0.0.0 (as
suggested earlier), the following DHCP address values are recommended:
DHCP Pool Start: 10.237.1.2
DHCP Pool End:10.237.3.254
DNS Server
Address
This entry is typically configured using the EON nameserver
command. If the
InterProxy is going to use a DNS server to resolve names, you must provide the
valid IP address of a DNS name server. Obtain the DNS server address from your
network administrator. (The universal DNS number is 199.191.128.104.)
User
Authentication
This option enables the YWS to require end-users to bring up a Web browser and
view an external page before passing any traffic through. The default is Off. If using
the Billing Manager module, turn this option On.
IP Address -
network to
exclude
This is optional. Occasionally a single physical network will host multiple logical
networks (IP address spaces). In some cases, the ETH 1 port connects to this type
of network. To handle this situation, the network exclusion option allows you to
specify one (and only one) additional logical subnet which the system identifies as
‘local’ to the InterProxy. This avoids interference in this IP address space and
prevents network conflicts caused by the InterProxy attempting to proxy for
machines in this address space.
In this field, specify any host IP address valid for the second logical subnet (on the
ETH 1 side). This field, together with the network mask you enter in the next field,
is used to identify the network to exclude (or bypass).
CAUTION
Once you configure the network exclusion option, users with foreign
addresses may gain access to network resources (such as printer, file
servers, etc.).
