RH 8: Which one? Ipchains or IpTables


I installed RH 8 onto my system tonight and am trying to get IP masquerading implemented to allow for other workstations on my network access to the Internet.

From my understanding Red Hat 8 does not use IpChains by default.
Upon looking at my system services, BOTH are enabled for my runlevel of 5.

Which is being used by default? Is one overriding the other?
Should I turn off IpChains?

Looking at the contents of IpTables, there is some sort of Red Hat specific script commands prefaced with RH-Lokkit in it. This looks very non-standard and I am wondering what the hell this crap is!

Will I be able to use regular IPTable commands?

Thanks!

You can only have one of them running!

type...
chkconfig --level 2345 ipchains off
service ipchains stop
rpm -e ipchains

The Lokkit prog has a few bugs (I'm being mild here)

A better interface is Firestarter.
An iptables tutorial is at http://iptables-tutorial.frozentux.n...-tutorial.html where you can learn what each of the command does.

That's what I thought Peter

By default on a new installation on Red Hat 8, IPChains AND IPTables are both running. This is a bug and I can't believe that since Red Hat decided to use IPTables, they didnt disable the damn IPChains service.

The scary part is, which one was actually running in precedence! I hesitate to say that this may be part of the problem of trying to get ip masquerading working on my end.

Yes, I think Lokkit SUCKS and is more like a wizard with limited use. The garbage it generates in iptable is useless

The really stupid bug I found in the Red Hat security level settings is the one that fails to retain the current setting of the firewall (lo, medium, hi). Geez, I can't believe RedHat let this one slip by. I mean this is what I pay Red Hat for isn't it? To come up with a nice installer, test out the applications and actually charge me for this!

Awful. Just awful.

The system security level application and Lokkit appear to accomplish the same thing - update the iptables file.

The no firewall setting deletes the iptables file
The low firewall and high firewall setting creates the iptables file with different levels of support.

Looking at Firestarter web page... looks nice.. thanks

Just to even the playing field,
iptables won't load if there are any ipchains modules in memory.
ipchains won't load if there isn't a config file to read,

So to be fair, RH did cover themselves, but what a way to find out about it, eh?
