Description: This object indicates whether a device forwards direct broadcast datagrams or not. More details of this object, please refers to RFC2644.
What is hpnicfIpBdstForwardBroadcast?
This setting controls whether the HPN-ICF device forwards IP directed broadcast datagrams, packets addressed to a remote subnet's broadcast address, a behavior governed by RFC2644 and historically restricted for security reasons since directed broadcasts have been exploited in smurf-style amplification attacks. An administrator typically sets this to notForwarding on internet-facing interfaces to eliminate that attack vector, reserving forwarding only for internal networks with legacy applications that genuinely depend on it. For example, with this set to notForwarding(2) on a WAN-facing interface, the router silently drops any inbound packet destined for a remote subnet's broadcast address.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.15.2.33.1.1 snmpwalk -v2c -c public <target> HPN-ICF-IP-BROADCAST-MIB::hpnicfIpBdstForwardBroadcast
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.15.2.33.1.1.1 snmpget -v2c -c public <target> HPN-ICF-IP-BROADCAST-MIB::hpnicfIpBdstForwardBroadcast.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11.2.14.11.15.2.33.1.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hpnicfIpBdstForwardBroadcast.1
