Can you tell us what it was that you changed? Someone else may need to
know, someday.
You're absolutely right. I guess I forgot my obligation in my excitement to
go home yesterday. ;)
Here's what I did:
1. cp /etc/defaults/devfs.rules /etc/
2. chmod u+w /etc/devfs.rules
3. vi /etc/devfs.rules: Added "add path pf unhide" to the
[devfsrules_unhide_basic=2] ruleset
4. vi /etc/devfs.conf: Added "own pf root:wheel" and "perm pf 0660". *
5. shutdown -r now
* I don't know if my permissions/ownerships for /dev/pf are correct, but I
looked at other devices and made a guess.
Anyone know what they're supposed to be?
Just noticed I don't have pflog or pfsync devices either, so I guess I'll
create those too.

It has been a while since I worked with iptables, but I have NEVER had
to reboot in order to make changes to it. That is just bizarre!
I never took the time to actually write my own iptables rules, but SuSE has
a built in mechanism that simplified it:
SuSEfirewall2. Basically you just have a fairly simple config file to edit
and SuSEconfig writes the rules for you.
In the O-Reilly book Linux Server Security (2nd Edition), it says "... all
you do is edit the file /etc/sysconfig/SUSEfirewall2
(in earlier versions of SUSE, /etc/rc.conf.d/firewall2.rc.config), run
SUSEconfig, and reboot". So I've been doing it that way
ever since. But after a quick Googling, it seems that maybe I don't have to
reboot and can just run
"/sbin/rcSuSEfirewall2 restart". Just an example of one of the times I
wasn't very thorough in investigating something. ;)
