Help needed setting up linux firewall

[neonfiremanqtip]

Hi,

I am trying to set up a linux firewall for my machines at home and followed this howto precisely, the only differences being the IP address and DNS servers provided by my ISP vice the author's, and I extended the IP address range provided by the linux server up to 192.168.1.199 (as opposed to the author's 192.168.1.10). I am running Kubuntu and used webmin to set up the firewall, etc.

I can access the internet from the server (that's how I'm posting now), and my client machine can use DHCP and grab an IP address from my linux server, but cannot access the internet.

My client is a windows machine, and when I ipconfig /all, I get:

IP: 192.168.1.199
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
DHCP: 192.168.1.1
DNS: 192.168.1.1

Any thoughts? Any other info about my setup needed?

I'm new to linux, and know enough about networking to be dangerous, but clearly not enough to get this thing working. Any help would be appreciated.

Thanks!

Can you get to sites by IP address?

You may have access, but the DNS is not forwarding properly. you can test that by using your ISP' dns server here

DNS: 192.168.1.1

instead of the one given out by DHCP
