Simultaneous Bridging and Routing
6-5
Simultaneous Bridging
and Routing
You can configure the OfficeConnect Gateway for simultaneous bridging and
routing. IP routing is configured if IP forwarding is enabled (see
Enabling IP
Routing
).
Bridging is enabled by adding a bridge network over the Ethernet and WAN
interfaces (see
Configure Bridging for the LAN and WAN
). Routing and bridging
are enabled for each destination in its remote site profile.
When configured for simultaneous bridging and routing, packets received are first
passed through the router for any configured protocols. If the packet can not be
routed, it is passed to the bridge, depending on the setting of the Bridge Firewall
function.
You can set the Bridge Firewall function of the OfficeConnect Gateway to any one
of three modes:
Discard Routed Protocols
Forward Unicast Packets Only
Forward Broadcast/Unicast Packets
Discard Routed Protocols
The Discard Routed Protocols mode is the default mode. If a protocol is configured
for routing and a packet for that protocol type is received from the LAN that is not
addressed to the MAC address of the OfficeConnect Gateway, it is discarded.
Additionally, broadcasts for the protocol are not passed to the bridge.
set bridge firewall
discard_routed_protocols
Use the
set bridge firewall discard_routed_protocols
command to configure
the Bridge Firewall to discard routed protocols.
Forward Unicast Packets
Only
If a protocol is configured for routing, and a packet for that protocol type is
received from the LAN that is not addressed to the MAC address of the
OfficeConnect Gateway, it is bridged. Other broadcasts for the configured
protocol are not bridged.
set bridge firewall
fwd_unicast_only
Use the
set bridge firewall fwd_unicast_only
command to configure the
Bridge Firewall to only forward unicast packets.
Forward
Broadcast/Unicast
Packets
Unicast packets for a configured protocol received from the LAN that are not
addressed to the MAC address of the OfficeConnect Gateway are bridged.
Received broadcasts (such as DHCP) are bridged.
set bridge firewall
fwd_bc_and_unicast
Use the
set bridge firewall fwd_bc_and_unicast
command to configure the
Bridge Firewall to forward both broadcast and unicast packets.
Packets received from the WAN do not pass through the Bridge Firewall. Instead,
they are delivered to the router or bridging function based on their encapsulation
