Nopes, definitely no. I would rather say that "Packet Filtering" is the primary job of a Firewall.

This is usually handled by a border router with outbound (egress) filtering. It checks the packet for addresses that do not match the network you are in and drops the packet from going out.
the following are the functions of a router 1. used for interconnections of networks 2. used for packet filtering 3. used for selections 4. used for setting up a wireless network
"A static packet filtering firewall is the simplest method of filtering traffic."
Handling Broadcasts, Error Logging, Debug packet filtering, & SNMP processing
a) Router is more expensive than Hub, Bridge & Switch. b) Router only work with routable protocol. c) Routing updates consume bandwidth. d) Increase latency due to greater degree of packet filtering.
Filtering is the process of analyzing the contents of a packet to determine if the packet should be allowed or blocked.
Unless your router has a mirroring port. So you can connect an internet filtering product (eg: WFilter) to the mirroring port in your router to do monitoring and filtering.
Answering "If a router recieves a packet that is does not know how to foward what type of route must be configured on the router to prevent the router from dropping it?"
The router discards the packet. The router forwards the packet via the default route
