You may want to recall what you specified during the install of your OS.
Also go to the website of your routers manufacturer and download the manual.
It will be in .pdf format most likely. Otherwise, you should be able to access help,
once you access the routers config pages. Most SOHO gateways allow you to disable
DHCP. or you can specify an IP address for your Linux box outside of the range of DHCP addresses.
If you want to use the GUI that comes with FC3, click on Applications>SystemTools>NetworkTools.
This will open the "NetworkDeviceControl
" dialogue box. Highlight the device you want to configure and click on "Configure"...(most often this will be eth0).
The "Network Configuration
" dialogue box will appear...there are several items of importance that you need to configure; the static ip address you have chosen for your computer, the subnet mask, the gateway address, and the DNS server IP address of your ISP. If you have signed up for a domain via dyndns.org (or similar service), you can also assign a fully qualified domain name to your computer. Lets do this step by step...
1. With the "Devices Tab
" active and your device (NIC) highlighted, click on the "Edit" icon...
This will bring up the "Ethernet Device
" box. Check "Activate device when computer starts"
Select the "Statically set IP adress" radio button...this effectively disables DHCP and you will now be able to enter manual IP address settings, for example IP address:192.168.1.100 /Subnet mask: 255.255.255.0 /Default Gateway address: 192.168.1.1...make sure that you select an Ip address that corresponds to the network on the router. You also may want to enable "Allow all users to enable and disable the device". Click on OK.
2. You will return to the "Network Configuration
" dialogue box...highlight the DNS tab...
Here you can specify the hostname for your computer and the DNS servers.
Lets say you created a domain called "derek.dyndns.org" and want to name your computer "alby". So you would enter "alby.derek.dyndns.org" (without the quotes) in the hostname field. The tricky part is what your primary and secondary DNS servers are. More often than not, you can use the Ip addresses that were given to you by your ISP. Some folks set up DNS services on their computer or even on the router/gateway, but that is more infomation I am willing to deal with right now. Once you have the correct info entered, return to the "Devices" tab. Click on "File" and save the configuration. Last but not least, make sure that the ethernet device is activated and check the status in the window.
is one of several organizations or .coms where you can sign up for a free domain name. The way it works, is that you are piggybacking on their domain, by creating a name (if it is available), and appending it to dyndns.org, as in derek.dyndns.org...DNS, (domain name service), maps easily remembered names to IP addresses. If your WAN IP address is 22.214.171.124 (just an example), I should be able to connect to that address via derek.dyndns.org....but your ISP is most likely assigning you a dynamic WAN IP address, which can change on a moments notice.
In that case, you need a mechanism to update the WAN IP address on your router with the DNS cache of dyndns.org. For that, you have to download and install a "client", that monitors the WAN IP address of the router from your computer, let's say every 5 minutes or so. If the IP address has changed, the client will take note of that and send an update to the DNS servers at dyndns.org. Dyndns.org has list of such clients.
If you have managed to follow me, have configured your router to portforward to your computer, and a few Hail Mary's, people from all over the world should be able to find services on your computer, such as httpd, ftpd, sshd, etc. and connect to them.
Please read up on security and firewalling a bit (or a lot, preferably), before you open up services to the world.
