I recommend to disable source routing and the following services: tcp and
udp small server, the finger service and the CDP.
All of the above are tools that can be use for getting information on your
network, hack into it and crash it.
have a good day

The ip redirects will stop icmp redirects that your router will perform.
The ip directed-broadcast will stop passing broadcasts as unicast. There are
about 6 or 7 ports passe.
The ip proxy-arp will stop the router from routing for a host that doesn't
have a gateway configured.
