Hans- Is this for your home network? If you are reading the Linux System Administrator Guid they are talking about not installing a firewall and DHCP on the same machine in a large network. If all you are trying to do is install a gateway and firewall for your home network I would suggest the following: Open the Mdk Control Center and set up Internet Connection Sharing. If you have two nic cards, have the one go to your wan and the other nic go to your local lan. The wizard will set up DHCP and caching DNS. As long as your ISP hands you an address when you connect on the wan, DNS will be available to the machines on your lan. I have a machine at home that does this, my machines on the lan use the Mdk box as their dhcp, dns, gateway and squid. Works very well and the performance is more reliable and faster than a LinkSys! I have an 8.2 box doing this now, I can't get 9.0 to work correctly, but once I get my boxed version I will play with it some more. -Scott > > the result of all these docs just now is, that I am confuesed - does not > know what I should do. > > would it be possible to give some helps in realizing these > installation-steps ? > > thanks once again > bye hans > > Am Don, 2002-10-17 um 21.41 schrieb Ron Stodden: > > hans privat wrote: > > > hi, > > > in a sysadmin-book I've read, that with kernel 2.4 the "iptables" > > > should be used. > > > > > > now I have done a lookup with lsmod and have seen, that there was NO > > > iptables but an ipchains. > > > > You have the iptables RPM installed.
