ipExtIfBackRtVerify
Module: BIANCA-BRICK-IP-MIB
OID (symbolic): BIANCA-BRICK-IP-MIB::ipExtIfBackRtVerify
OID (numeric): 1.3.6.1.4.1.272.4.5.3.1.18
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object activates an additional check for incoming packets. If set to on, incoming packets are only accepted if return packets sent back to their source IP address would be sent over the same interface. This prevents packets being passed from untrusted interfaces to this interface.
What is ipExtIfBackRtVerify?
This writable control enables reverse-path verification (anti-spoofing check) on an interface. When set to 'on', the device rejects incoming packets if a return packet to the source would depart on a different interface. Enabling ipExtIfBackRtVerify = on on an untrusted WAN interface prevents spoofed packets from entering the LAN.
Examples
