Dear SuSE Wizards,
Anyone have a favorite tutorial that they reference for setting up iptables? I just finally got myself trained on ipchains but I guess I'm going to have to get retrained.... An online resource would be best, but a good book will do, as well.
I have Robert Zigler's "Linux Firewalls" which helped get me up and running for a couple of years, but that is mostly about ipchains--iptables isn't even in the index.
His web site, http://linux-firewall-tools.com/linux/firewall was awesome for creating what appeared to have been a decent firewall, though I never could get it to come up on it's own (always had to manually start it, which was a pain). I'm been ruined by point and click!!!
Unfortunately, even with support for both ipchains and iptables in the 2.4 kernel, I think it's time to "upgrade" my knowledge base rather than being content to live in the past...
Seems like you know a bit of what you're doing, so have a look at Rusty's Remarkably Unreliable Guides at http://www.netfilter.org/unreliable-guides/ There are even figures of which table/chain is called where in the routing process ;-) Also, the man page of iptables is quite exhaustive once you know what you want.
