It would, IMHO, be best if hosts acting as firewalls didn't allow
source routing *through* them. I'm sick of having to hack this out of
kernels rather than having an option, and yes, its strictly necessary
if you are building an application level firewall. IMHO, if you don't
have ip forwarding on, you shouldn't forward packets, PERIOD.
