I recently set up a linksys router/firewall for my cable modem and have been having major problems. I decided to use static IP and the info is as follows:

Linksys 192.168.1.1

Linbox 192.168.5.5
Mask 255.255.255.0
Def Gway 192.168.1.1
NS1 167.206.112.138
NS2 167.206.112.3
NS3 167.206.112.4

I have a windows machine and all of this works well. Ican even ping the Linux box. However, the Linux box can't ping anything else on the network; gateway, windows box. It can ping its own local address and its own IP. The interface is brought up fine at boot also. Any help is appreciated this is driving me crazy. Thanks!

It looks like your IP address and subnet mask are mismatched, causing your router and Linux box to effectively be on two different networks. With a netmask of 255.255.255.0, the first three octets of each machine's IP address should be identical. The usual convention when using static, non-routeable
IP addresses (such as the 192.168.1.x range) on a internal LAN is:

Network = 192.168.1.0
Router = 192.168.1.1
Machine #1 = 192.168.1.2
Machine #2 = 192.168.1.3
Machine #3 = 192.168.1.4

What's the IP of the Windows box?

I completely forgot my netmasking-mostly from working at a place where we use a class B and flat address space-thanks for the reminder!
