[TUT] Setting a static internal IP (Windows and Linux)

[Mark]

This is how to set an internal static IP on your home network. This is of use when you're port forwarding on a DHCP network.

Windows XP

Start
Control Panel
Network and Internet Connections
Network Connections
Right click "Local Area Connection" and click properties
In the "This connection uses the following items:" box, double click "Internet Protocol (TCP/IP).
Then select, "Use the following IP address:"
IP address: 192.168.2.100
Subnet mask: 255.255.255.0
Default gateway: 192.168.2.1

To find your DNS servers, open cmd and type "ipconfig /all"
"Use the following DNS server addresses:"
Preferred DNS server:
Alternate DNS server:

Click OK, OK then you're good to go.


Linux

Running as root

Code:

sudo su

Your main network configuration file is /etc/network/interfaces

Code:

nano /etc/network/interfaces

Find and remove the dhcp entry

Code:

iface eth0 inet dhcp

Add the new network settings

Code:

iface eth0 inet static
address 192.168.2.100
netmask 255.255.255.0
network 192.168.2.0
broadcast 192.168.2.255
gateway 192.168.2.254

Save and close the file, then restart the network

Code:

sudo /etc/init.d/networking restart

Defining new DNS servers

Code:

sudo nano /etc/resolv.conf

You need to remove old DNS server assigned by DHCP server:

Code:

search Belkin
nameserver 192.168.2.1

Save and close the file.


I recommend keeping a backup of the files incase something goes horribly wrong.
