Ubuntu Networking :: Configure My Box To Connect To A Modem In Bridge Mode?
Jun 27, 2011
How would I configure my box to connect to a modem in bridge mode?
I have a server at home that im migrating over to be the default-gateway/router. I have everything else setup (dns,dhcp etc) now just need the ppoe part, or so i beleive?
I have two interfaces. eth0 (lan) and eth1 ready to connect to the modem.
The modem is in bridge mode ready to go.
What is my next step? Are there any good guides, I didn't find any.
I just installed Lucid Lynx Ubuntu on my computer. I love it, but I do not see how to configure my dial-up modem and connect. I'm hoping it's still possible. Here's my hardware.
I have OpenVPN running on my Ubuntu Server just fine. I can connect over the Internet and access all my resources on the LAN via bridged mode perfectly. My server only has one LAN card and sits behind my router, which means it has a private IP address of 10.1.1.2....Which brings me to my question. I want to open up access to my friends via OpenVPN, but I don't want them to be able to access other machines on my LAN (e.g. 10.1.1.20). However, I do want them to be able to talk to each other and pass broadcasts (old LAN games), as well as my laptop (let's say 10.1.1.7).I've tried using iptables to block traffic to the LAN (such as .20), to no avail. I've been reading up and it seems as though iptables won't even filter the traffic, as it's passed at a lower layer. Is this true? If so, what do you recommend I do in order to prevent my buddies from accessing the rest of my LAN while siumultaneously allowing broadcasts pass for some very old Windows LAN games (we're talking Windows 9.
I have installed CentOs 5.4 for Snort sensor , on the location where i intend to place the Snort sensor to listen for internal firewall leg (LAN) the switch doesn't support port mirror so i would like to create with 2 nic's bridge and pass trough the firewall internal leg my question how do i set such configuration.
I have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
my both linux and windows has 2 network cards each.
basicaly it is vLan cards, each server has 2 network cards. one to main switch and one to local IP.
data will be going like below:
internet ----------------> eth0 --> linux --> eth1 ----------------> Windows.
i have vLans on both servers. And i need cross connection setup. And use linux in bridg mode / cross connection .
actualy i want to use Iptable rules to filter bad packets and forward good packets to windows. i have scripts how to forward packets to windows. but the problem is i dont know how to setup both servers in this topology. and how to make linux as bridge.
All it should be in transparent mode. Not in NAT mode.
i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

i have 3 servers in 2 dcs as follows; server 1 (dc1 - dmz) --- server 2 (dc1 - internal) --- server 3 (dc2 - internal) Now I have an application in server1 that have to connect to port 44000 in server 3 but dc refuse to open connection saying they do not open connections between dmz and dc2 (i have no say over this).
However I can connect to virtually any port from server1 <-> server2 and also server2 <-> server3. Is it possible to do something like;
server1 <-> server2 <-> server3:44000 using nc to get the app work.
...to be able to configure the usb modem in my linux computer. As I've been using Linux there onwards, I didn't mind any longer.
Now I plugged the usb into a windows computer but the driver installation routine doesn't start. It's obvious that's because I deactivated the cd mode. How do I bring it back?
how to configure Huawei 3G modem (ec325) in ubuntu 10.04, even i tried with gnome-ppp / wvdial which unable to connect, shows "ppp deamon died" and disconnected at the end of dial.
I have started using ubuntu 11.04 desktop edition recently. And sadly i dont have an internet connection. I have an USB modem of Huawei. But I cant configure that in ubuntu. Im from india and using Reliance Netconnect 1x EC121 modem. Can anybody please tell me how to configure this modem so that I can connect to the internet? Due to lack of internet connection im not being able to download any updates or codecs. I have started using Ubuntu only 2 days ago..
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
While communicating with cpanel , they said they don't support on any NAT router based network. To host website with cpanel internet should be connected directly with modem (no router) I have a dell poweredge server and recently brought PCI modem. I have 8 IP static addresses from my ISP. cpanel as they said that they don't support networking.
I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
I've just spent 2 days of extensive lurking how to solve this problem. Namely, i have ZTE usb modem, model MF626 T. The sofware provided with it works only under windows. What i tried first was to download hso.ko module (copied to the /lib/modules/`uname r`/kernel/drivers/usb/serial/). Then i downloaded hsolinkcontrol and HSOconnect. Unfortunately, i didn't get those /dev/ttyHS* ports that should appear. Only /dev/ttyUSB*. I blacklisted option module. Then changed occurences of ttyHS* to ttyUSB* in .py sources for HSOconnect. what i get is the popup interface GUI that has "connect" button disabled. Then i tried to set up connection via gnome-ppp. The usb modem was automatically detected as /dev/ttyUSB1. But when i supply telephone number that i got with the stick, i get message after "Sending: ATM1L3DT*99*" ->"no carrier found". Then i tried to copy the other two modules i found on the net-airprime.ko and usbserial.ko. I've renamed the option.ko and old usbserial.ko in order to use them later if needed. And also i've put in /etc/udev/rules.d/ some scripts i've found on net, used to mount and unmount ZTE modem. None of all that worked, and somehow i have the feeling i've messed up everything. What i just posted above is the sum of everything i googled out. I would be very glad if someone would help me out with this. I usually like to spend some time lurking and googling, but this is simply taking too much time...
My wireless modem has disappeared from the connection list at the top of the page. Strangely, a guest connection on that same modem is still visible but won't connect. I added the modem back in as a new connection and it was added to the list but it was greyed out and I still can't connect to it. The problem could, of course, be in the modem but I have no way to check that. Reset is not working. Lan connection to the modem works fine. This is the second time this has happened in the last week and I ended up reinstalling Ubuntu. This gave me back the wireless connection. I don't really want to have to do that again. Is there anything I can check in Ubuntu?
how to connect my modem to the Internet, the help file on my Ubuntu 9.10 does not match the features available. I am using a modem from Starcomms (a local CDMA services provider in Nigeria) made by Epi Valley.
I have been working for the last week trying to connect my serial hardware external modem (courier 56K v.everything) within an Ubuntu 10.4 environment. I live in the boonies where I am presently forced to use dial up, so this has got to work, else I cannot update Ubuntu or download software. After trying various suggestions, which my very limited Linux skills fail me, I opted for the suggestion that I download gnome-ppp, install and then use it. Seeing how I cannot download it through Synaptic Package Manager (which I was advised to but can't as it is my Linux computer that I am trying to connect).
I downloaded the zipped file (gnome-ppp_0.3.23_Oubuntu2.tar.gz ) to a USB stick, copied it to the home directory and then extracted it, wherein a new directory was created with many files in it. From here I have been unable to install it through the command line (not sure how), nor have I been able, as was suggested, to install it via the Synaptic Package Manager (can't get it to see the file, not sure how to). I need explicit (Newbie) instructions on how either to connect the modem without gnome-ppp, or instructions on how to get gnome-ppp installed.
I am new in Ubuntu Linux. I am using Acer Aspire 4740. And I have purchased HSDPA Mobidata as internet modem. But I cannot connect it. How can I connect it and use internet using this modem?

I have been using an ethernet ADSL Westell modem for years and would like to upgrade to a newish Allied Telesyn USB Modem AT-AR206 in Fedora Core 10. The modem power goes on when plugged into my pc and lsusb shows that it has been recognized with this:
Bus 002 Device 003: ID 1110:9022 Analog Devices Canada, Ltd (Allied Telesyn) ADSL Loader
I used system-config-network but don't have the option of adding this new hardware.
I have an ADSL Internet connection with static IP.I connected through PPPOE from my modem to my ISP.I need to ssh from outside of my home to my home, But i don't know to use which connection between my computer and my modem.(dhcp ,static , bridge or ....)
I wonder what is your opinion about the best method for using an ADSL modem. Router or bridge? I did read some articles that say "that the bridge mode gives you more stability and has higher speed". Is that true?
Furthermore, you suggest any alternative to "pppoeconf"? I've been getting this errors ( in the plog), related to "PAD packet loss" and also errors in "PPPOE Discovery", even when I am connected. When this things starts to show up on the log, my connection "pauses" for some seconds. I do not feel very safe with this program.
I've successfully install kvm with private network (nat) up running. I want to switch the kvm network using bridge mode (or host-interface), but do not success. env: nic iwl4965/ kernel 2.6.27.8/ debian etch upgrade to lenny/ kvm 0.9.1/ hardware hp 6910p The doc I follow up is at [URL] The way how i set it up is to modify /etc/network/interfaces by adding following section to enable br0
However, the problem is the guest os, which starts with -hda k1.img, can not access to the internet. Is there any step I miss? or it is because wireless does not support bridge (I've heard doc says that wireless does not support wireless bridge)?
