net.inet.icmp.icmplim change issues

[Mike Hunter]

Greetings programs,

I'm working on making a freebsd shuttle box to do throughput testing at
remote sites on campus.  There's a couple things I'd appreciate some
advice about.

I'm interested in turning off the icmp response limit.  In
/boot/loader.conf I have the following:

net.inet.icmp.icmplim="0"

Yet when I boot 
% sysctl -a | grep icmpl
net.inet.icmp.icmplim: 200
net.inet.icmp.icmplim_output: 1

Doh!  Would I need to recompile my kernel for some reason, or is
/boot/loader.conf not the right place.  Is this something I really
shouldn't be doing?

Thanks,

Mike
