Fedora Networking :: Computer Behind 2 Routers Can't Connect To Internet?
Mar 6, 2011
I have so many _wired_ devices that I can't get by with just 4 eth cable outlets anymore, so I thought I'd hook up an older router that I don't use as a way to get extra places to plug devices into.
Now it looks like:
Internet
then cable modem
then router1/wifi + (1 eth NAT storage)
then router2 + 4 eth0 computers:
(legacy FC5 box)
(legacy F11 box)
(updated F13 box)
(windoze)
All of the computers EXCEPT the FC5 box are fine (my def of "fine" is I can ssh to and from the other computers and to outside computers, and browse the web).
The FC5 box, however, can ssh to and from computers inside the network just fine, but can't get any kind of web browsing. Nor can it ping to the outside. I get a "Network is unreachable" error. I'm not using a proxy, not knowingly, and my firewall settings haven't changed...it certainly hasn't been blocking port 80 before.
what's the best way to go about adding more ethernet when you need about 7 cables. I'm not really excited to buy a router with 8 ports or anything like that, especially when this seems to _almost_ be working just fine.

I have two routers. One is a Verizon ProLine and the other is a Dlink. My setup is myComputer-Dlink-ProLine-Internet. I'm trying to get port 80 requests from the outside, access my http server on myComputer. I tried port forwarding on both routers, but that didn't work. I also tried to make the ProLine treat the Dlink as a DMZ, but that still doesn't work.

I connect to multiple wireless system each day but when I encounter a Linksys-n router the computer will recognize it and connect but does not go online.
Does this give any clue for why it will not connect?
Code:
802.11a/b/g
System wireless is: Toshiba Satellite M115-S3094 with Intel PRO/Wireless 3945ABG (802.11a/b/g), Ubuntu 10.04

I have a modem connected to my router (pfsense on 192.168.1.1) which is then connected to a wireless AP (192.168.1.253). A number of PCs pick up the wireless and all is well.I've just received another broken PC that I've kicked into life and was going to run a FreeNAS box with it to back up a number of the PCs on the network. I've actually hooked this up via ethernet to my "server" PC (192.168.1.125 on its wlan NIC). Its all set up so that the server eth NIC (10.42.43.1) is connected to the FreeNAS box (10.42.43.2) and the FreeNAS box can ping both interfaces of the server, the router and the net, and any other box on the 192.16.1.x network. The problem is that I can't for the life of me get any of the 192 boxes to ping the FreeNAS box. I'm presuming its a routing / gateway issue with the server box but being pretty damn hopeless with these things I've been stumbling about breaking things.

I am using Ubuntu Studio 10.04 LTS and I am experiencing the following problem: my computer loses its Internet connection and appears to require several reboots to re-establish an Internet connection.
As suggested on a similar post relating to wireless connection loss, I supply the output of sudo lshw -C network
*-network
description: Ethernet interface
product: NetLink BCM5789 Gigabit Ethernet PCI Express
vendor: Broadcom Corporation
[Code].....
Note that I have REMOVED my wireless card in case there was some kind of hardware conflict or failure. I am using a wired connection through a Linksys WRT54G router that is supplying an Internet connection to another computer and an IP phone without any problem.
When I run the command network-admin (or select System > Administration > Network) I can see only 3 tabs (General, DNS and Hosts) It seems that the Connections tab has disappeared (and I believe this happened when I upgraded from Ubuntu 9/Karmic Koala). If I click Help it shows me that there should be 4 tabs, not 3.
The connection dropping began prior to my decision to upgrade. In fact it took several attempts to complete the upgrade. Should I attempt to re-install the upgrade? I am not sure how to do it without losing my connection. When I visit System > Administration > Update Manager, I am informed that my system is up to date.

I have F14 on a laptop and can't see the laptop screen very well, unless I put my face like right up against the glass, is there a way I can login to my F14 laptop using my windows desktop computer?
whats the easiest way to do that?
I used to use nomachine in previous versions, is that method still used in F14? can't seem to find the FreeNX package anymore.
I used these instructions in previous versions: [URL]
which you'd think would still work in F14, but not sure what happened to FreeNX
otherwise, how do you do it using vncserver? I didn't do it that way in the past because I didn't understand how.
using XFCE window manager in F14 on a windows 7 desktop
Laptop: HP Pavilion dv6-1350us
Desktop: custom build Asus computer using a 23 inch Samsung SyncMaster 226bw LCD display

I recently set up a network of computers via Ethernet, all of which use Fedora 10. I would like to be able to get any computer on the network to hook up to the internet.(I think the solution is now figured out - see below, on page 2, "problem solved")

I have two computers and I'm trying to get them to talk to each other, but after I installed Fedora 14 on this computer, my other computer can't connect to this.
[code]...
Same with DAAP I'm using rhythmbox to both broadcast and listen to the DAAP, and the rhythmbox on the remote computer cant connect here either. ssh and VNC are working on the other computer as well, I can connect to other computers using ssh on both computers, and I can VNC over to the other computer without any problems, its the traffic going myway that seems to be hitting a roadblock. is it possible that since I installed a different system (was Ubuntu Natty before, and I was using all three services before I installed Fedora), I need to do something on my remote computer so that this won't crop up?

Here's the issue: from time to time I have to take away my son's access to the internet, so I exclude his laptop from my wireless Linksys router. Works like a charm, or it did until he discovered that my neighbor also has a wireless router, and hasn't secured it.
So my son sits in the corner of the house closest to my neighbor and uses their internet.
Is there any way I can tell his laptop to NOT access a particular router? Or even better, to only access my router?

Every time I start up my Samsung NC10 the wifi doesn't seem to find my wireless router at all and instead tries to connect to my printers network. To solve this I need to disable and re-enable wireless until it automatically connects. I know this isn't exactly a major problem, it's just getting pretty annoying. I'm using Fedora 11 btw.

i have a Server, which has 2 nics installed. Each of those is connected to a router, which is connected to internet. On the server, i have apache, maillserver and im-server running. On the other hand, also squid, dansguardian and clam are running. so now: via eth0 i would like to have just the traffic, which is requested from outside (the big bad internet..) to my server (apache, mail, etc). via eth1 i would like to have all OUTGOING (also to the big bad internet) from the server, which is requested by a internal client. And of course all requests to my own server
both nics shall route their traffic to their own router. For better comprehension please consult the enclosed graph. Until now, i did not find a good solution, the default route is set to the traffic from eth0, if not, no external request will find back to a client do you have a idea how to handle this the easiest way?

I installed fresh copy of fedora 11. I can't activate or deactivate ethernet from system>Administration>Network. Why is this............I can connect to internet directly by enabling network icon on right topmost corner. Even doing so dosen't guarantee connection at times. What could be wrong here ? Also my network icon shows it is disconnected whenever I start my computer. Cant fedora 11 just connect to the internet while it boots ?

I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

I've been trying to connect to the internet in Fedora 10 for the last week but can't figure it out. The OS has automatically connected to the internet a couple of times but now does not connect at all. The LAN ROM Boot option is enabled in my BIOS and am using a speedtouch 585v7 router provided by my ISP, I have an ADSL router and it's a standard ethernet connection to the router. What do I do to connect to the internet

I have just installed Fedora 10. After the installation I was able browse the Internet. However, I did a update: yum update and downloaded 287 updates. However, when I rebooted I could no longer connect to the Internet. I went to network manager and looked at the details of my connection. Everything ok there. IP address, DNS, etc. However, I cannot connect. I have windows xp running on the same system. I can still connect, so there is nothing wrong with my Internet connection.I am using Fedora 10 2.6.27.12-170 There is one thing I have noticed when I shutdown is I see this: "Network manager Int PIC disabled" However, this is only displayed for a few seconds before the computer swiches off.

When I fire up my F10, I get connected to the Internet through wireless automatically. I jus wanted to experience how the CLI- Command Line Interface world is and to test the text based internet apps like elinks,lynx etc.. So I changed the runlevel to 3 in my /etc/inittab file. Now when I fire it up, it gives me the terminal.
The problem is I am unable to connect to internet. How should i connect to the Wireless Access Points.. n also here internet is under a http proxy ...so how to configure the connection.
I have tried a lot, like
Code:
I have used this part of script many times in runlevel 5 i.e X mode under gnome for spoofing my wireless adaptor's mac id by adding a line before starting the NetworkManager service.
Code:
I have also tried something like
Code:
But this one shows nothing(no output just stays blank) I dont get why it doesnt work under runlevel 3..

2 days ago I did a fresh install of Fedora on my computer to be dual-booted with Linux Mint. The first time I did this install a few weeks ago, I did all of the updates, rebooted (internet still fine) and when I rebooted again, Fedora could no longer connect to the internet (but could still see the networks and ostensibly connect to them). I fixed it then by manually setting the BSSID/IP/DNS/etc.
And this happened again on the new install! This time it took out the internet connection in Mint too. I tried manually setting the connection settings, but that didn't even work for a while. So, last night, thinking that the install might be the problem, I reinstalled Fedora. This morning I finally got my internet to connect on Mint, but I'm concerned that if I do all of the updates on Fedora I'm just going to end up back at square one with zero internet connection.

Actually I would like to connect to the internet with a Kubuntum, but I cant. I tried the KDE version of Fedora, and the Network Manager worked perfectly. I would need this basic Network Manager application, of Fedora KDE, I can not connect to the internet with my computer (have cable neither) so I would like to download it, and burn to a dvd. I have been googling around, but haven't found a version which I could install. I hope that it is possible to install on my Kubuntu this software. I would be really greatful if You could tell me from where can I download it!

I am trying to connect to a wireless internet but can't. I previously used linux ubuntu and my wireless card worked. I am guessing that it should work with fedora then too. Is that correct? Do you have any suggestions as to what I should do to get the wireless internet working again on Fedora 12? Or what I should do to get usb wireless adapter to work.
