FW-1 doesn't do it.. which firewalls do?   I believe most
rely on the OS to take care of it, or expect it shut off at the
routers.  Besides, you want to be able to configure that off
in the OS, as another item on your hardening list to make
it fail closed, or as closed as possible.

The ablity to detect source route packets is
"generally" provided by the firewall software that one
installs. The driver in most of the firewalls detcts
the IP options in the IP packet and takes a decision
on the necessary action as configured.
The NT OS or the Unix OS do not detect source
routed packets. So one would need another software
to detect such packets, and one would in all
probability do this with a firewall software....

Scientists have announced discovering a meteorite which will strike the 
earth in March, 2028.  Millions of UNIX coders expressed relief for being 
spared the UNIX epoch "crisis" of 2038.
