I'm working towards replacing an old firewall box with a new one. The
old box runs Red Hat Linux 9. I have an iptables script that works well
under the Red Hat 9 version of iptables, but which does not seem to work
under the Fedora Core 4 version. For example, the script defines the
external DNS server for my ISP, and when I run it, I get messages that
various external servers were not found, e.g.
" 'server.myisp.net' not found"
which indicates DNS failures which in turn indicate there is some sort
of firewall scripting problem I am hitting.
It could be that my network card (eth1) is bad. I've replaced it and get
the same error messages. Also there is no connectivity when I try to
bring up a web site using the new router box. It could be that current
versions of iptables work differently than in Red Hat 9, which I realize
is an ancient, unsupported OS.
Is there a resource anywhere devoted to using Fedora Core 4 for
firewalling and routing? With something of a tutorial, since I obviously
need one?
Thanks
