I run my machines behind a router with a hardware firewall, but I was wondering if anyone is hooked directly to the net at home or at work. If at work do you use Suse Linux as a firewall? If at home, do you have a lot of attacks that show up in the firewall log?
use hardware & software firewall. the hardware one,built-in to the router, & i don’t have very many attempts to get in ( say that now, bet someone will now try 
) so far no problems,even the software one is ok

I have only observed hack attempts on port#22.
We run our family laptop quite often at various locations during our travels. Many of these places either don’t have hardware firewalls, or their firewalls are deliberately disabled to as to not block the activities of customers. Because our laptop is only powered intermittently, we don’t get many attacks at all in the logs.
There was a time when I had a desktop (running openSUSE) plugged into the net directly, and when port#22 was open, I had a lot of hack attempts on that port. But now adays we have a hardware firewall inbetween the desktop and the web, and the firewall has port#22 blocked (with instead a high arbitrary port number mapped to port#22) and all hack attempts have stopped since then.
What’s the significance of port #22? I have file sharing on and open in the firewall, but no guests as we have to log in, to allow my OpenSuse machine to work as the server at home.
Do you know what port is opened for file sharing?
Port 22 is the standard port for SSH.
Here’s some more standard ports.
Why do you have to log in to get openSUSE working as server? Are you using Samba/NFS/etc?

We have to configure our laptop users with the firewall on (duh).
I mean, you never know what they’re hooking into.
And yes… you should see a gazillion attacks… the norm… nothing
out of the ordinary.
IMO the term embedded firewall is more fitting. You’ll find those embedded firewalls are sometimes running a version of Linux with iptables, the only difference from your desktop being a different, low-power CPU, stripped down OS and programs, and loading from flash memory.
It’s all hardware (and software) anyway.
