Fedora Users — Re: forcing a specific IP

I followed the instructions and restarted the computer (was it a

must?
I thought Linux doesn't require that).
With ifconfig I saw that the new IP was given - but no internet
connection was established.
What else could I miss?
Did you set your gateway in your Linux box?? and what about your
DNS??
[<Yigal>] The only thing I did was to set the IP.
1) you have to set the Gateway on the PC's on your network.... 2) you have to start NAT (Network Address Translation) on the PC that
is
the gateway to the Internet
3) BUT WHAT IS MORE IMPORTANT: YOU HAVE TO START A FIREWALL (IPTABLES)
ON THE GATEWAY BOX
I suggest to have a look at www.netfilter.org and then come back here.
You will be on the Internet in a really short time....
[<Yigal>] I use router (edimax) - and it general it works fine. I set the pool to be between 192.168.2.110 till 200 (for the PCs that take the IP automatically). For the Linux machine - I want to have specific IP (e.g. 192.168.2.100). Currently the Linux works fine with auto-IP. I know how to change it to the needed IP(192.168.2.100) - what should I put in mask? 255.255.255.0 ? and what about the DNS field ?

you can check which DNS are currently in your /etc/resolv.conf while the machine is surfing on the internet (if you want to fix them). It is not clear to me why it is not surfing if you fix only the IP .... because I understand that now you are getting DNS from your router.

Note: my previous post referred to a routing made with a Linux box (i.e. two network interface) and doesn't apply to your layout
