SuSE SLES 10: YaST Firewall
I have to use the YaST firewall as my, well, firewall.
The standard settings and everything that I change in the setup tool, add or change quite a lot of iptables settings. It's impractical to change setting afterwards with iptables, since YaST adds large amounts of lines to it, making even reading it somewhat complicated.
What I'm missing is some sort of file, where those settings are saved. I'm used to Debian systems, where those files are loaded with iptables-restore from a file that was usually generated by iptables-save.
Is there such a file on SuSE SLES? And if yes, where is it?
And where does SLES save those settings?
On Debian, I've got the following settings in one of my iface definitions in /etc/network/interfaces:
Both rules files were generated with iptables-save.
I assume there is something similar on SLES, but I couldn't find where it is.
opensuse IP tables load a boot
I just spent a day try to get openSUSE11.0 to load some custom iptables settings in conjunction with the SUSEfirewall at boot. I've got it working now so I thought I'd share:
1. forget about trying to set up a script to run like a service with chkconfig. It just won't work (even with S99!). I suspect the firewall flushes the settings later, after these rc.d scripts are executed, it's not clear how or why the settings get ignored but trust me - they will be ignored.
2. You'll need to edit /etc/sysconfig/scripts/SuSEfirewall2-custom. Put the custom iptables commands where appropriate, details are given in the file itself. Do read what is in the file because there is no man page for this.
