Hi, I had absolutely no luck with the HOWTO or the SuSEFirewall script (it wouldnt forward either !@#!@), so I created my own script system. Attached is a tar.gz file containing a directory called fw2, inside this directory you will find: fw This is the perl script that actually sets up the firewall. allowed_tcp This file lists all tcp ports allowed into the external interface. allowed_udp This file lists all udp ports allowed into the external interface. internal This file lists all inside hosts/networks you want to masquerade. While this script isnt that robust, it is simple enough that you should be able to do what you need to do by building on to it. If you need any assistance please contact me at secureaustin@consultant.com. Regards, HD Moore http://nlog.ings.com (Like Nmap?

Hello!
We are currently trying to build a packet filtering firewall using SUSE Linux 6.2 and ipchains. The hardware used is a Pentium 133 with two Level One NICs using the Realtek 8139 chipset.
From what we read in the literature (Firewall and Ipchains HowTo, several articles in the german magazine ct etc.) it seemed quite manageable, but then reality struck.

We are quite desperate (and my boss is losing patience), so any ideas are highly welcome. Might it be useful to try some other network adapters? Is there something we have overlooked? Is there a fault in the HOWTO?
Best regards
