Normal outbound traffic has an internal source IP address and an external destination IP address. Traffic with an internal source IP address should only come from an internal interface. Such packets coming from an external interface should be dropped. Packets with the source-routing option enabled usually indicates a network intrusion attempt. Router information exchange protocols like RIP and OSPF should be dropped to avoid having internal routing equipment being reconfigured by external agents.

Inbound packets with an internal address as the source IP address.
These packets are likely to be generated by internal hosts, and their traffic needs to be allowed to reach other internal hosts and systems. Blocking this traffic would disrupt normal network communications and potentially prevent internal hosts from functioning properly.
