Ok i need a firewall for redhat linux 7.3
I have looking into iptables, but do not understand them, so want to use a firewall instead
Does anyone know any good websites i can find a firewall with a gui
Thanx, Matt.
If you just looking to create a dedicated firewall, go to www.smoothwall.org.
It's a linux firewall that is administered via a web interface. It allows for VPN's, Snort Intrusion detection, Squid Proxy server among an extensive loging system. It's a pretty small iso download and there is a GPL version.
I use it and love it.

ok, is it a firewall which i can install on
the same machine as linux, or is it a
firewall that has to go on a seperate
machine
if so, will a pentium 90, with 16 meg of
ram be ok for it, as the only other machine
i have is the server

dont be so dirty lazy. if you dont want to know how your system works and learn to configure it please keep using windows.
to correctly configure you always need to know how packets are being routed and it makes absolutely no difference, if u use a hw fw or iptables. go to linuxguruz.org and download a firewall script. read through it, read the iptables manpage and edit the script to fit your needs.nobody lerned iptables in 2 minutes but it is worth the effort. if you are not willing to learn about software you should definitely not be running a server because you endanger your data, your connection and other people on the web (ddos attacks...)

sorry...misread your post...i somehow thought u wanted to run a server behind the fw.. (getting old i guess)
still you should take a look at the web site i pointed you to learn about iptables.

It is a separate server. I run mine with a 166 and 64 megs of ram and a 2 gig drive. Runs like a dream.
I don't think you would have a problem getting it to run on a Pentium 90. The ram could cause a few problems, but it's always worth the try. It may work since it is not initializing an X server or anything.
You will need to NIC cards though. One to connect to your internal network, and one to connect to your isp.

ok thanx, i have a few network cards lying around i can use so thats not a problem
will have another look at iptables
have spent a while looking through the iptables how tos, and most seem to think that you already know the basics, and go straight to the more difficult stuff
when i get some money together, i will have to get some books on it

Armin,
I can understand your point concerning knowing the operating system and taking the time to learn.
However, my personal feeling is that I prefer to have a dedicated gateway/firewall rather than my one server. I hate single point of falure. Also, I like many, am still learning and tend to make mistakes. If I take the internet access down, I wouldn't hear the end of it!
I prefer to have the protection of the dedicated firewall while I play around with the server.
Just my 2 bits!

If you are still learning about iptables and really don't know what you see when looking at the output of a utility like tcpdump then IMO you should not be administering web connected machines.I admit it may be an extreme POV but..
Anyone can make a mistake..just make sure it doesn't happen twice or three times..

iptables is not THAT difficult. u just have to know that network traffic happens in packets, that they all have source and destination addresses and source and destination addresses. once u understand that youre one big step closer to understanding what iptables does. it checks incoming packets for their src/dst addresse and ports and then it does whatever u tell iptables to do with them. accept them, forward them, drop or reject them. basically thats all (basically :))

correction:
[...]that they all have source and destination addresses and source and destination ports.
sry :)
