I use RaspBMC as OS which stores its "persistent" iptables configuration in
/etc/network/if-up.d/secure-rmc and I presume it's applied when the eth link goes up (e.g. after boot).
If I futz with the rules in the console, how can I reload the "persistent" ones (and discard the futz'd rules)?
There's no 'service' per se for iptables, and trying to
service networking restart doesn't seem to help.
I've already locked myself out twice trying variations of
ifconfig eth0 down; ifconfig eth0 up (a reboot helps :-) )
