this happens only when going through the NAt code.
I just tested and only time when it crashes is when one of the ends is in
( i haven tested with both endss in NAT but thats rare to find anyways )
so to resume:
one of the networks is NAT-ed
ping -R a NAT ed ip from a real ip ( it has to go through the fw )
or ping -R a real ip from a NATed one
fw has to be below hop 9 on this road otherwise it doesnt work.
Result: complete kernel panic
my ip nat rules are rather simple .
so i belive anyone should be able to reproduce the problem.

i belive this is an old problem since this is not the first time i heard
ping ing with ping -R from through a firewall machine make the firewall go
into kernel panic
tried to kill idle task
does anyone know a fix for the problem ?
or a set of rules that will fix the problem ?
i believe ping -R works only on about nine hops... what bothers me
is that nine hops can be a lot of subnets :(
Thanks for any help
