- loeg 14y agoWhile true, I'd like to note that the article's author does have OOB access.
- andrewvc 14y agoFWIW I never understood UFW over straight IP tables, is it really easier to read?
- luser001 14y agoIMHO, yes. At least on Ubuntu, it's never been too clear to me how I should save my rules so that they come back on startup. The ufw man page is pretty decent.
- leetrout 14y agoI've not tried anything complex with UFW so I still use iptables on my bastion host that handles my vpn tap. It's not terribly complex to make rules come back on startup (but probably more involved than one would hope). For anyone else that followed the thread to this point- this advice on bringing iptables back up on reboot worked for me http://rackerhacker.com/2009/11/16/automatically-loading-iptables-on-debianubuntu/ http://rackerhacker.com/2009/11/16/automatically-loading-ipt... YMMV
- hahainternet 14y agoThis is how I run iptables on a sufficiently large network of machines. The advice is not complete. IPv6 is real and really works most of the time these days. Back up your ip6tables to a file too. I like /etc/firewall-4.conf and /etc/firewall-6.conf but it's down to preference. Know about iptables-apply too, lest you be caught unaware.
