1 Fast Ethernet Menu
The fields of the FAST ETHERNET menus are described below.
The FAST ETHERNET menu provides access to the following submenus:
■FAST ETHERNET/EN1-0 > bis FAST ETHERNET/EN1-3 >, depending on the con-
figuration of the switch in the SWITCH CONFIGURATION menu.
As per default the four-port-switch operates in Single Interface Mode and is
to be configured via the Ethernet interface FAST ETHERNET/EN1-0.
■FAST ETHERNET/EN1-4 >:
As per default this Ethernet interface is assigned to the separate Ethernet
port ETH5/DMZ.
■SWITCH CONFIGURATION:
For the assignment of the Ethernet interfaces to the available Ethernet
ports at your device:
– the four-port-switch (ETH1 to ETH4)
– ETH5/DMZ interface.
Split ports Your gateway offers the possibility to have the four switch ports operate as one
interface (Single Interface Mode) or to operate with a logical separation and in-
dividual configuration of the four switch ports (Split Ports Mode).

1 Fast Ethernet/en1-x Menu
The fields of the ETHERNET/EN1-Xmenus are described below.
The Ethernet port is a physical interface for the connection to the local network
or to external networks. You give your gateway the IP addresses at which it is
reached in the LAN resp. WAN in the FAST ETHERNET ➜ FAST ETHERNET/EN1-X
menus. As long as these parameters are not entered in your gateway, it cannot
be addressed by other hosts in the network.
If your gateway is connected to an IP network that consists of two subnets, you
should enter a SECOND LOCAL IP NUMBER and a SECOND LOCAL NETMASK for the
second subnet.
ETH1 - ETH4 When separating the switch ports (ETH1 - ETH4), each separate port is assi-
gned the required Ethernet interface in the field ASSIGNED INTERFACE. For each
assigned Ethernet interface one FAST ETHERNET/EN1-Xmenu is displayed in the
FAST ETHERNET menu, which allows a completely independent configuration of
the interfaces.
ETH5/DMZ Assigning a dedicated Ethernet interface is also available for the Ethernet port
ETH5/DMZ. As per default this Ethernet port is assigned the Ethernet interface

FAST ETHERNET/EN1-4, the menu of which provides for equal configuration op-
tions.
The FAST ETHERNET/EN1-Xmenu consists of the following fields:
Note
The Ethernet ports of the switch are shipped in Single Interface Mode. The Eth-
ernet interface FAST ETHERNET/EN1-0 is assigned and is preconfigured with
LOCAL IP-NUMBER 192.168.0.254 and LOCAL NETMASK 255.255.255.0.
If you split the ports of the switch in the SWITCH CONFIGURATION menu, this pre-
configured LOCAL IP-NUMBER together with the LOCAL NETMASK are assigned to
the ETH1 port configured via the FAST ETHERNET/EN1-0 > menu.
To be able to reach your device with split ports, insure whilst splitting the ports
that the Ethernet interface FAST ETHERNET/EN1-0 with the prconfigured LOCAL
IP-NUMBER and LOCAL NETMASK is assigned to a port that can be reached via
Ethernet. In case of doubt carry out the configuration via a serial connection at
the Console interface.
Field Description
IP-Configuration Possible values:
■Manual: Default value. IP address and net-
mask must be entered (default value).
■VLAN: Allows the assignment of the Ether-
net interface to a ➤➤ VLAN.
■DHCP: Your gateway obtains, among other
values, IP address and netmask from a
DHCP server.
local IP-Number IP address of your gateway in the network at
the interface.
local Netmask Netmask of the network in which your gateway
with LOCAL IP NUMBER is located.
Second Local IP Number Only for IP CONFIGURATION Manual or VLAN
and after entering a LOCAL IP-NUMBER.
Second IP address of your gateway in the net-
work.

Fast Ethernet bintec User’s Guide 7

Second Local Netmask Only for IP CONFIGURATION Manual or VLAN.
Netmask of the network in which your gateway
with SECOND LOCAL IP NUMBER is located.
DHCP MAC Address Only for IP CONFIGURATION DHCP.
MAC address of the corresponding Ethernet
interface, e.g. 00e1f906bf03.
Some providers use hardware-independent
MAC addresses to assign their clients IP
addresses dynamically. If your provider has
assigned you a MAC address, enter this here.
DHCP Hostname Only for IP CONFIGURATION DHCP.
In this field you can enter the host name
required by the provider. The maximum length
of the entry is 45 characters.
Encapsulation Defines the kind of header added to the IP
packets that run over this interface. Possible
values:
■Ethernet II (conforms to IEEE 802.3)
■Ethernet SNAP
■none (default value)
You can generally retain Ethernet II (default
value when having entered an IP adress in
LOCAL IP-NUMBER). The interface is called e.g.
en0-1 for Ethernet II and en0-1-snap for
Ethernet SNAP.
MAC Address Only for IP CONFIGURATION Manual or VLAN.
Here you can assign the interface another MAC
address. This is only required for configurations
that are more complex than the basic configu-
ration, e.g. 00a0f906bf03.

ARP and "Back Route Verify". The menu is only displayed if a LOCAL IP-NUMBER

Brief description of routing
The ➤➤ gateway receives ➤➤ data packets, each of which contains the des-
tination host IP address. On the basis of the entries in the routing table IP ➜
ROUTING, the gateway decides which route to use to forward the data packet to
ensure that it arrives at its destination as quickly and cheaply as possible (with
the fewest possible intermediate stations). The entries in the routing table can
be defined statically or the routing table can be updated constantly by a dynamic
exchange of routing information between several gateways. This exchange is
controlled by a so-called Routing Protocol, e.g. RIP (Routing Information Proto-
col).
RIP (Routing
Information Protocol)
Gateways use ➤➤ RIP to exchange information stored in routing tables by
communicating with each other at regular intervals to mutually supplement and
replace their routing entries. The R3000 Series gateways support both version
1 and version 2 of RIP, either individually or together.
Gateways can be defined as active or passive gateways: active gateways store
routing entries sent by other gateways and offer their routing entries to the oth-
ers via ➤➤ broadcasts. Passive gateways accept the information from the ac-
tive gateways and store it, but do not pass on their own routing entries. The
R3000 Series gateways provide both variants.
IP accounting This option is for activating or deactivating IP accounting messages for this in-
terface. If IP accounting is activated, accounting messages are generated (and
entered in the biboAdmSyslogTable), which contain detailed information
about the IP-connections of this interface.
Back Route
Verification
This term conceals a simple but very powerful function of the R3000 Series
gateways. If Backroute Verification is activated for an interface, incoming data
packets are only accepted over it if outgoing answering packets would be routed
over the same interface. You can therefore prevent packets with fake IP ad-
dresses being accepted – even without filters.
Proxy ARP The ➤➤ Proxy ARP function enables the gateway to answer ➤➤ ARP re-
quests from its own LAN acting for a defined WAN partner. If a host in the LAN
wants to set up a connection to another host in the LAN or to a WAN partner but

1
10 bintec User’s Guide Fast Ethernet
Fast Ethernet/en1-x Menu
doesn’t know its hardware address (MAC address), it sends a so-called ARP re-
quest into the network as a ➤➤ broadcast. If Proxy ARP is activated on the
gateway and the desired target host can be reached e.g. over a host route, the
gateway answers the ARP request with its own hardware address. This is suf-
ficient for establishing the connection: The ➤➤ data packets are sent to the
gateway, which then forwards them to the desired host.
The configuration is set in the FAST ETHERNET/EN1-X➜ADVANCED SETTINGS
menus:
Table 1-2: ADVANCED SETTINGS menu fields
Note
Ensure that Proxy ARP is also activated at the defined WAN partner.
Field Description

net interface. Possible values: see table
“Selection options for RIP Send and RIP

sible values: on, off (default value).
Proxy ARP Enables the R3000 Series gateway to answer
ARP requests from its own LAN acting for a
defined WAN partner. Possible values: on, off
