2 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 OCR 812,
it is bridged. Additionally, ARP broadcasts for IP addresses other than that of the
OCR 812 are also bridged. Other broadcasts for the configured protocol are not
bridged. To configure the Bridge Firewall for this mode, use the command:
received from the LAN that is not addressed to the MAC address of the OCR 812,
it is bridged. Additionally, ARP broadcasts for IP addresses other than that of the
OCR 812 are also bridged. Other broadcasts for the configured protocol are not
bridged. To configure the Bridge Firewall for this mode, use the command:
set bridge firewall fwd_unicast_only
3 Forward Broadcast/Unicast Packets:
Unicast packets for a configured protocol received from the LAN that are not
addressed to the MAC address of the OCR 812 are bridged. Received broadcasts
(e.g., DHCP) are bridged. To configure the Bridge Firewall for this mode, use the
command:
addressed to the MAC address of the OCR 812 are bridged. Received broadcasts
(e.g., DHCP) are bridged. To configure the Bridge Firewall for this mode, use the
command:
set bridge firewall fwd_bc_and_unicast
Packets received from the WAN do not pass through the Bridge Firewall. Instead,
packets received from the WAN are delivered to the router or bridging function
based on their encapsulation and on the state of the MAC-Encapsulated Routing
parameter in the remote site profile.
packets received from the WAN are delivered to the router or bridging function
based on their encapsulation and on the state of the MAC-Encapsulated Routing
parameter in the remote site profile.
In general, a packet received in a routed encapsulation (i.e., IPCP or Routed RFC
1483) is delivered to the router. A packet received in a bridged encapsulation is
passed on to the bridge. If MAC-Encapsulated Routing is enabled, the received
(bridge-encapsulated) packets are delivered to the router.
