Fedora Networking :: Routing To Server In VirtualBox Using Billion Modem
Sep 10, 2010
I am having trouble for routing port 80 from a Billion adsl modem to a guest server in VirtualBox. There are quite few different changes from my last setup so I kind of confuse which one is wrong.
I used to use have the setup belowusing modem Linksys WAG354G use static ip 192.168.1.100 for my machine use static ip 192.168.1.102 for my guest VirtualBox server guest OS is serving http listening on port 80 i use bridge from my host OS for VirtualBox set my modem to direct all traffic on port 80 to 192.168.1.102 host OS was Fedora 11
now I useusing modem Billion 7404VNPX use same static address and configuration host OS is Fedora 13
main issue is I cannot reach the guest OS if I navigate to my modem ip address. (e.g. http://192.168.1.1) if I change the modem to direct all traffic to my host OS ip address (192.168.1.100) it works nicely.
I have tried to disable and enable the firewall without any luck.

My USB-modem and my freerunner phone is no longer recognized by fedora. Last time this happened I just reinstalld Fedora because I had no id�a what caused the problem. But now I recognized that virtualbox was the last package I installed before the problem occured.
I tried to uninstall virutalbox but the problem remained. Is there a way to reset all the network settings without reinstalling fedora?

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 have a firewall, this consists of three NIC's:
Code: eth0[192.168.0.2] eth1[192.168.1.2] and eth2[10.10.165.2]
I am trying to ping eth0 from eth2, but I am not able to succesfully get a response from pinging the device, I am using:
Code: ping 192.168.0.2 -I eth2
I have tried to insert routing data into the routing table, but it still doesn't work

i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through

I have a server that has two NIC cards installed eth0 and eth1 we use a linksys router (192.168.2.1) which runs DNS for our LAN. I have installed Squid on the server which runs Ubuntu server (8.04 Hardy) w/ GUI. I can surf the net on the server with google chrome configured to use proxy server localhost:3128...works good. The router is wire directly to eth0. I have my laptop (running Ubuntu Hardy) wired to eth1 and I want to be able to surf the Internet through my server. From my laptop, I can ping 192.168.2.100 which is the IP address assigned to eth1[?] by my router. I assume I need to establish a route from my laptop to my server. I would like to archive this via the CLI and I am not having any luck thus far. If I add static IP addresses to eth1on the server and eth0 on my laptop will this simplify the process? How can I add a route which will allow me access to the Internet via my laptop?

I have one main subnet 192.168.50.0/24 with a defaultrouter 192.168.50.1 connected to the internet. I have an NFS server on that network. Everything is working as desired and machines are able to see each other and access the internet.
Now, I would like to add two more interfaces to the NFS server (running Slackware Linux), each on its own different subnet, say 192.168.51.0/24 and 192.168.52.0/24. The clients on those new subnets should also be able to access the internet (through the router 192.168.50.1). how to setup routing? Do I need any additional hardware router in between, or just a software configuration on the NFS server?
On a side note I have VLAN capable switches (couple of ProCurve 1800-24G) and would like to separate the three subnets using VLANs instead of using three separate switches.

I have the following setup:
Location A:
Internet -> ISP 1 -> Firewall 1 (external IP address) -> Web Server 1 (internal IP address)
Location B:
Internet -> ISP 1 -> ISP 2 -> Firewall 2 (external IP address) -> Web Server 2 (internal IP address)
I want to find out if I can failover to another location without having to make changes on the DNS server. Just by redirecting traffic from ISP 1 router to ISP 2 router.

I've just set up an LTSP server, with all its clients on a separate subnet to my main network - the main network is 192.168.1.x, and the LTSP clients are all 192.168.2.x. My LTSP server has 2 NICs, one on each network, and is merrily forwarding normal IP traffic from the clients to the rest of the network. I have a client/server application that has a server on one machine, and clients locate and attach to it using multicast protocols. The server is on the main network, and any other machines on the network can locate and talk to the server quite happily. The LTSP clients, however, cannot - I assume because the multicast communications aren't being forwarded by the LTSP server. How I can get this working?

I have set up a Virtual machine on a dedicated server from 1and1. I hoped to use a bridge to give the vm direct access to the internet but 1and1 do mac filtering and so the only option is to use NAT.
I used Virtual Machine Manager on my Ubuntu 10.04 machine at home to install Debain Lenny on the vm on the server using KVM and all went well. I put it on a virtual network 192.168.100.0 and i can access it from the host and i can access the internet from the guest using NAT that libvirt set-up.
I bought another ip address from 1and1 with the hope of forwarding packets to the new ip address 11.22.33.02 to the guest vm.
I have tried all sorts of routing rules using iptables without any success.
my virtual network is on virbr1 the guest ip is 192.168.100.50 my external network device is ip say 11.22.33.01 on eth0 with the secondary ip say 11.22.33.02 on eth0:1
Here are the latest rules i tried:
Quote:
iptables -t nat -A PREROUTING -d 11.22.33.02 -i eth0 -j DNAT --to-destination 192.168.100.50
iptables -t nat -A POSTROUTING -s 192.168.100.50 -o eth0 -j SNAT --to-source 11.22.33.02
iptables -A FORWARD -p tcp -i eth0 -o virbr1 -d 192.168.100.50 -m state --state NEW -j ACCEPT
iptables -A FORWARD -t filter -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT

IN LAN default GW box I have a routing rule of 172.17.1.0 192.168.180.100 255.255.255.0 UG 0 0 0 eth3 that sends packets matching 172.17.1.0/24 to eth3 etc. When I ping 172.17.1.50 - it goes correctly when ping is issued in the same box (LAN GW) - falls through to default rule when the ping is done in LAN's boxes i.e. it goes to the LAN GW box and then to Internet incorrectly instead of going to eth3 and 192.168.180.100.
Is there any way of seeing why the packet matches or not the routing rules?

I have just installed Fedora 10 on an old laptop and was quite impressed with how smoothly it all went ... until it came to setting up networking!
I have battled for three days now and I'm almost there;
- installed updated firmware to the built in Broadcom 4306 wireless network adapter
- got NetworkManager to work with a static ip address by manually editing the ifcfg-wlan0 file
- managed to get the WPA security to work
The only problem I am left with is that there is no default route; if I set one up using: ip r a default via 10.1.1.1 dev wlan0
Then everything starts working.
If I try to add routes using the NetworkManager gui interface they dont get saved (no suprises there then! ).
I have tried creating a route-wlan0 file in /etc/sysconfig/network-scripts/ but this seems to be ignored by NetworkManager.
Since the NetworkManager GUI is almost useless, does anyone know if there are any other configuration files I can manually modify to get a default route set?

On a Fedora 11 machine, I configured ppp0 on eth0 and ppp1 on eth1, each one is connected to a modem, I also defined ppp0 as the default gateway.. Should I do anything else to load balance the 2 connections or will ppp1 take some of the load by default? Should I add any other routing rules? If yes then please tell me what should I add, keeping in mind that for each pppoe connection both the pppoe address and the remote address are not static so I actually needed some scripting to change the default gateway each time the remote pppoe address changes.

I want to implement routing using fedora 14. The following is how I arrange my computers -
[PC1]<=======>[ROUTER]<=======>[PC2]
And the following are the configuration -
PC1 : (Tiny Core Linux)
eth0 192.168.2.2/24 (netmask 255.255.255.0)
ROUTER (FC14)
eth0 192.168.2.1/24 (netmask 255.255.255.0)
eth1 192.168.4.1/24 (netmask 255.255.255.0)
PC2 (Tiny Core Linux)
eth0 192.168.4.2/24 (netmask 255.255.255.0)
On the ROUTER I have set the ip_forward=1 and eth0.proxy_arp=1 and eth1.proxy_arp=1
then I run the following command :
route add -net 192.168.2.0/24 gw 192.168.2.1 dev eth0
route add -net 192.168.4.0/24 gw 192.168.4.1 dev eth1
On PC1 I executed the following :
route add -net 192.168.4.0/24 gw 192.168.2.1 dev eth0
and for PC2 I run the following
route add -net 192.168.2.0/24 gw 192.168.4.1 dev eth0
After doing those things, I can't ping between PC1 and PC2... but both can ping the router...

I'm currently reading through the Linux Advanced Routing and Traffic Control HOWTO from lartc.org, and I'm wondering whether anyone knows of a file where I could keep qos rules persistent across a reboot, similar to /etc/sysconfig/iptables for netfilter. Should I just write my own script, or does something already exist?
By the way, iproute-2.6.29-4.fc12.i686.

I have a problem with the activation of routing under fedora. The problem lies exactly in the file ip_forward who I didn't not change the value to 1. When I use the command echo 1> / proc/sys/net/ipv4/ip_forward. They appears not granted permission. Knowing that I use the root account.

I don't know what I'm trying to achieve falls into 'routing' or 'Bridging'???I have two network ports (with static IP ) and I would like to forward RX packets of one to the other.
I have done this in Windows by enabling a service called 'routing'.Is there something similar in Fedora 11? I am pretty sure there are a few thread explaining these but I am just not educated enough to find one that makes sense to me, so Please excuse me for starting a redundant thread and point me to it?

I cannot figure out how to setup my HSIA USB Modem (TataPhoton+ from Tata teleservices)in ubuntu server. This device works fine with Ubuntu 9.10 desktop edition. Just a few clicks in network manager does the job, but how to achive the same in ubuntu server which have no GUI

find and install modem driver for the Alcatel X200 USB modem?
I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.

Basically, I wanted to use the Bootp (PXE) protocol to boot a machine (my laptop) from my network instead of using USB/DVD boot medias to reinstall if need be. My router being a piece of crap, I couldn't setup the DHCP server to allow PXE packets. Confirmed from the manufacturer that it is not possible. Well for a $140 router, you would expect the opposite. Anyways, here I am with a small machine setup with Slack, no desktop environment (only CLI) and connected to my router (which I deactivated the DHCP) so the machine can act as a DHCP server. It works very well. However, I would like to install a few other utilities into that machine and for them to work, I need to put the machine between my cable modem and my router. Basically, here's the topology from outside):
Internet (ISP) --> Modem --> DHCP machine --> Router (no DHCP - acting as a switch) --> computers & printers
The problem is that I cannot connect to the modem from the computers on the network. Also I cannot access the internet (go on the WAN side) from the computers. From the computers (namely my laptop), I can ping the router, but cannot ping the interface where DHCP broadcast. Also I cannot ping the modem. From the router (using the web config page), I can ping the DHCP broadcast. From the DHCP machine, I can ping the modem. In the DHCP server, I setup the eth0 (the interface where the modem connect to) as a DHCP assigned IP so it can obtain the IP from the modem. The eth1 (the interface where DHCP broadcast) is static. All my machines obtains a IP from the DHCP machine without a hiccup.

Tried turning firewall off, i tried port forwarding tcp port 22, but it still doesn't work. Also am unable to ping modem over WAN, i can ping the modem locally though. Tech support claims pinging and ssh is not part of the internet so they wont support it in any way.

I have installed the KDE spin and am liking it so far. Except for the fact that I cannot get onto the internet. I rely on this ZTE USB wireless modem for internet and that just would not get recognized in Fedora. Plus, my Windows installation is down and I would love to keep it that way if at all possible.
I have followed a few instructions on this particular problem. I have modified the menu.lst file to account for the usbmodserial and product. The usb_modeswitch program has also been installed and the usb_modeswitch.conf file has been edited with the values I got from the 'lsusb' command's output.
But the curious thing is that when I actually execute the usb_modeswitch command, I get a message saying that there are no drivers for the ZTE device. Which means that I cannot go onto the wvdialconf part of it at all. Basically at this point I dont have a modem, according to Fedora. But it does get recognized as a ZTE device. That tells me that there is something right about what I have done so far and may only need to do a few tweaks here and there.
PS - I am based out of India and this is a Tata Indicom Photon (NOT Photon Plus) connection for which I have a USB device which acts as a modem.

When I use Ubuntu, my DSL modem correctly gets the hostname I call my computer "mertensia", but I'm having issues with Fedora. Yet, when I look at the name assigned by the modem (using URL... in a web browser),I need the PC Name to be mertensia, because otherwise it will complicate how I ssh immensely.
