d. Radio2 (ad hoc) Reachback will be configured to use the BreadCrumb device’s second radio (if any)
in IEEE 802.11b ad hoc mode.
3.5.2. MODE
This dropdown selects the type of reach back to configure. Available options are:
a. Automatic
In Automatic Mode, the interface attempts to obtain an IPv4 address using DHCP. If it obtains an address,
reachback is configured to use Gateway Mode; if it does not, reachback is configured to use Bridge Mode.
b .Bridge
In Bridge Mode, the reachback interface is configured to exist on the same network as the BreadCrumb
device’s other interfaces. Packets are forwarded into or ou tof the BCWN through this interface as necessary.
c. Gateway
In Gateway Mode, the reachback interface is configured to exist on a different network than the BreadCrumb
device’s other interfaces. Out bound NAT is configured so that any BCWN traffic destined for the reachback
network appears to originate from the reachback interface. Any inbound traffic from the reachback network
must be sent through a forwarded port (see the Section called Forwarding Settings)
Unless the Alternate Gateway checkbox is checked (see below) the BreadCrumb will assign itself the
additional IPv4 address of 10.0.0.1.
d . Gateway (Ingress)
In Gateway (Ingress) Mode, as in Gateway mode, the reachback interface is configured to exist on a different
network than the BreadCrumb device’s other interfaces. NAT, however, is configured in the direction
opposite to that of Gateway Mode. Inbound traffic from the reachback network appears to originate from the
BreadCrumb, and outbound traffic from the BCWN must be sent through a forwarded port (see the Section
called Forwarding Settings for details)
e. Disabled
Disables reachback regardless of the selected interface.
3.5.3 . ALTERNATE GATEWAY
If the BreadCrumb is in Gateway Mode and this checkbox is not checked, the BreadCrumb device is considered a
‘Primary Gateway’ and assigns itself the additional address of 10.0.0.1 (the gateway address provided by the
BreadCrumb DHCP servers). There may be at most one Primary Gateway in a BCWN.
Alternate Gateways do not assign themselves the 10.0.0.1 address, and provide their own addresses as a gateway
to their own DHCP clients.
Tip: If you are running a BCWN with multiple gateways, disable DHCP on all non-gateway BreadCrumb devices
for a simple form of load-balancing.
3.5.4 . ESSID
For reachback using the’Radio2’ or ‘Radio2 (adhoc)’ interfaces, this is the ESSID to which the BreadCrumb
device will attempt to connect.
3.5.5. WEP KEY
For reachback using the ‘Radio2’or ‘Radio2 (adhoc)’ interfaces, this is the WEP key that will be used for the
reachback connection. If a WEP key is not required for wireless reachback, leave this field blank.
