be sure you have your RouteD enabled in Linuxconf, and with your setup, it
sounds like you have to have masquerading setup also. I had the same prob
with my server when I first got it setup, those 2 settings took care of
everything. They do have a great progoram, called PMFirewall, which is
available at http://www.pointman.org/PMFirewall/. I use it on my server,
have not had any problems with it. It's run from the command line, but it
is a wizard of sorts. It will setup your masquerading & firewall, and it
will prompt you for what ports you want to leave open, and what you want to
close. It only takes a few minutes to get it up & running, works great.
That is cheating however, since your not doing your scripts yourself. ;)

Subject: ipchains question
Hello all,
What is the basic ipchains command that allows internal computers to
make use of a redhat 6.2 machine gateway for browsing the internet.
I've been playing around with ipchains using different commands, but
don't seem to beable to get my internal machines to browse the
internet. I've read the Howto and man pages, but I just want to get my
internal machines browing first before I even move onto tightening
security and such. My ethernet cards are working, I can ping off both
ends (outside onto the internet and internally to clients). My internal
client machines have private ipnumbers, same subnet as internal gateway
card, my isp dns numbers are in place. Am I missing something? Do the
network cards need to be lined up a certain way (internal eth0, external
eth1 is how I have it now)? Ipchains is set up, I can issue commands
and then delete the chains. I have even got it to block ping packets,
but no browsing seems to work from my client ends. Do I have to give
the browsers on my internal machines port numbers, or is the gateway
configuration enough?
Thanks ahead of time,
Paul
