Hi everyone.
We are a small international school with 22 computers on a lan with 7.3, samba, squid and a fast adsl internet connection. We cannot get SuSE firewall2 to let anything happen at all. It blocks everything. Everything works perfectly without the firewall. We have to make a decision soon as to the amount of time spent trying to get the firewall working (thanks to the patience of all on a related thread on this list) and whether we need it or not.
What will happen if we don't have it?
Thanks, Steve.
Sometimes nothing will happen.... then again... I run Smoothwall ( http://www.smoothwall.org ) as my firewall and internet router for a small home network. I couldn't get SuSE Firewall2 going either. My SNORT log (keeps track of hack attempts) on the Smoothwall machine keeps a record of intrusion attempts 24 hours per day. Some days there are more attempts than others. The most common attempts I get on my system are Port Scans, and Back Orifice scans. Generally, most scans are looking for open ports on Windows machines, but open ports on a Linux machine are just as vulnerable. A firewall can be looked at as a must have these days. As a suggestion... if you are having trouble with Firewall2, take a look at other options. The beauty of Linux is that you are not limited to one solution. Smoothwall works nicely if you have a spare 486Dx or P1 laying about. PMFirewall ( http://www.pmfirewall.com ) works nicely as well as a replacement for SuSE Firewall2 when you can't get things working. C.
