I want the eth0 address to be the gateway for accessing the internet on wlan0.
How do I setup static routes?
I'm not too keen with networking...
Code:
I'm trying to setup routes for a gateway that resides on a different subnet. Our ISP leased us a block of IPs and told us to route through the current gateway, which is on a different subnet than our current block of addresses. To test, I've enabled one of the new addresses on one of the existing machines, which works. That machine has an address on the same subnet as the gateway, however.
The gateway address is 24.111.1.177 One of the new addresses I'm trying to use is 96.2.192.130, netmask= 255.255.255.240, broadcast= 96.2.192.143 Obviously, I can't just specify that gateway in /etc/network/interfaces without some routing, which is where the trouble I'm having is. The machine I'm trying to set this up on is part of 2 networks - one internal, on two different NICs.

It has to be my static routing is not right. This is a confusing area to me. Right now my routes are

How do I add a route that doesn't go away after a reboot? I tried adding to /etc/sysconfig/network-scripts/route-wlan0 and /etc/sysconfig/static-routes but neither of them did anything when I restarted network and NetworkManager. route command does not show the new route that I added. I tried this too - routes.html and there were no errors but the new route doesn't show up with the route command.I added "192.168.13.88/255.255.255.255 via 192.168.13.101 dev wlan0"

What i would like to know is what is the point of accepting routes from your neighbouring AS(ISP)?My ISP has given me a default gateway, and no matter what I want to reach on the internet I have to go through that default gateway, so why populate the routing table with soo many routes?also, as i understand it, there are 3 kinds of routes that you can accept, those are full routes, directly connected routes and default routes. What is the diffrence between them and again how do they affect routing since my network only has the one default gateway?

Andreas Vinther, 1977, from Denmark
I'm trying to establish a connection between two seperate ADSL LANs (coming into the house, but from separate ISPs) to a situation where all hosts on either LAN will be able to reach any host on eiher LAN WITHOUT having to use an excess of plastic routers around the house, and please no Wireless bridges. WiFi will only be available as Access Points.
I've heard that Debian does this kind of static routintg / RIP stuff quite well. And I just happen to have one lined up in the right place, that haven't got at snowballs chance in hell of running WINXP or above. But it kills at textbased datamanipulation/forwarding/rerouting/dropping/scanning ... so I'vew made up my mind. That is what I want to do... Now how do io get around doing stuff like that.
The Debian box is connected to both networks: Hostname: AsusAnd
(192.168.1.0/24 - TDC network)
and to
(192.168.15.0/24 - Profiber network)
Needless to say, but both netmasks are 255.25.255.0 hence the /24 The respective router's LAN addresses are 192.168.1.1 and 192.168.15.1 My Debian are locked to the following IP's (reserved DHCP):
eth0:192.158.1.56 via DHCP from 192.168.1.1
eth1:192.168.15.177 via DHCP from 192.168.15.1
So far so good - Now here we go ! This is not a scenario where i'd like to always want all network-packages to travel the shortest path, nor NESSESARILY use the other ISPs gateway if the first is down or slow, although that'll be super nice.
I suspect that'll involve router-protocols like RIP. I'll be super pleased to get some guidelines there as well, as i suspect it'll be quite easy to implement once everything else is in place. Although RIP isn't our main goal, it probably comes as a close second. I think we all would like as stable and fast a connection as possible.
I was actually so naive that i thought if i added two static routes to the two routers x.x.1.1 and x.x.15.1, that my problems would automatically be solved by my Debian box, and that it would automatically act as a gateway when the routers send their packages for the other net. As long as i was connected to both LANs at the same time.
Note: I haven't changed or tweaked the Debian kernel to do routing. this is a simple stable install from the net-inst.iso of Debian 5. I'd like to keep it that way unless there's no way around it.
my routers have static routes to each other (WITH PROPER CABLING), configured as follows:
(On router with LAN 192.168.1.1)
[static route] to 192.168.15.0 with nmask 255.255.255.0 going throuhg gateway 192.158.1.56 ( Taken from above info ) - metric around 2
Similary on my other NIC directly cabled to another switch ---and-then-to-another---> Router

I need to change the static configuration, like I 169.254.0.0, I don't know how it got there also I want to delete 192.168.1.1 from a static gateway. How can I do this?
I'm running Ubuntu 10.04 and my setup is as follows:
As you can see, I am directly connected to router 192.168.25.1, and so my ip address is 192.168.25.101. I want my ip address to be 192.168.13.101, and make router 192.168.13.1 my gateway router. Is this possible under the current physical layout (I do not want to have to connect directly into 192.168.13.1, but keep my computer where it is at)?
When I run tracepath, it shows 192.168.13.1 is one hop away.
What I've tried:
The problem is under this manual setup, I cannot ping 192.168.13.1 and running command netstat -rn returns the following:
I have a fedora 14 box which has a static IP and I can not contact the internet or even my gateway router.I know it has to do with my kernal IP routing table but I can not find the command to do what I need...Here is my kernal IP routing table

My gateway is 192.168.1.1 and my static IP is 192.168.0.2.
Is there a standard config file for saving static routes or "ip route" commands? i lose my static routes after every "/etc/rc.d/rc.inet1 restart".rc.local wouldn't be a good idea, because it's not run automatically after "/etc/rc.d/rc.inet1 restart"
View 5 Replies View RelatedI've been trying to setup an IPSec connection between two routers, but am having trouble with the actual packet routing.
My setup currently is two local networks (192.168.1.0/24[netLANA] and 192.168.0.0/24[netLANB]) that are connected to their own routers (192.168.1.1 and 192.168.0.1 respectively). The routers are both connected to the 194.26.1.0/24[netWAN] network. I wish to setup an IPSec connection between the two routers, to act in tunnel mode between the two local networks.
The first router is a linux box (on the netLANA network) that I am setting up using the ipsec-tools, and the other is a Netgear ProSafe FVS318G (on the netLANB). I've set them both up to have the same configuration for IPSec. Also, on the linux router I have setup a route like this:
Code:
$ route add -net 192.168.1.0/24 wlan0
So that all traffic destined for the netLANB network will be routed to the wlan0 interface (netWAN in this case, and therefore over the tunnel).
My problem is that if I ping from any host on netLANA, I can see the ICMP reply comes back to the linux router, but it doesn't get back to the original host.
From the linux router, here is the tcpdump of the ping:
Code:
$ tcpdump -n -S -i any

I have setup a second machine with slackware 13.37, it is a "supermicro" which I picked up though my work. the idea was to set it up as a gateway and gradually expand my knowledge of sub networking, iptables, forwarding and the like. after a couple nights of forum searching and "o'reilly" book reading I am still unable to get a proper route working thru the "supermicro" to our dsl router.
What is setup?: I will start from my main machine simply calling it slackbox
slackbox: has two ethernet cards which i have given static ip's to
eth0 192.168.2.16 and eth1 192.168.3.11
eth0 (192.168.2.16) is connected to a switch and then to our dsl router, it is working, I am using right now to work on this forum.
eth1 (192.168.3.11) is connected to the "supermicro" thru a cross-over cable, it also is working, pinging the "supermicro" works.
default gateway on slackbox is set to be 192.168.3.10 (the supermicro)
I only set slackbox's default as 192.168.3.10 when testing to see if the supermicro gateway will work
supermicro: also has two ethernet cards which i have given static ip's to
eth0 192.168.3.10 (this is the card with the cross-over cable connected)
pinging 192.168.3.11 (the slackbox) works.
eth1 192.168.2.24 is connected to our switch as well, it is working, pinging our dsl router works.
default gateway on supermicro is set in rc.inet.conf to be 192.168.2.1 (which is our dsl router)
All my machines have two ethernet cards. This has just made it easy for me to test the setup while still having internet access on slackbox. Yet when testing the gateway from slackbox thru supermicro I am getting "Destination Host Unreachable".
setup 2 gateway in my email server(opensuse).
now i wan to setup 2 internet lines for my email server, which mean that either one of the line is down, i still can receive mail from another line.
Example
Internet line 1 = ISP1
Internet line 2 = ISP2
my email server got 3 nic which...
eth0 = 192.168.1.2 (255.255.255.0) (from ISP1 GW 192.168.1.1)
eth1 = 192.168.2.2 (255.255.255.0) (from ISP2 GW 192.168..2.1)
eth2 = 168.168.1.2 (255.255.0.0) (connect to local LAN)
now existing GW set on the server is 192.168.1.1, mail receive and send through ISP1. now we wish to set somethings that once the ISP1 line is down, the server will auto switch to ISP2 gateway and continue send and receive mail without manually change of settings
I have been searching google for a while now and have not found exactly what I am looking for. I would like to use my fresh install of ubuntu server 11.04 as my router/gateway for my home. I am not an expert at linux by any means but I can usually figure stuff out. I believe I need iptables, bind, and a few others probally. It eventually will also be a samba server but I have done a little with samba before. I do have 2 network cards, my router at the moment is starting to die and would love to have a more powerful router. I would also like to figure out how to do port forwarding in the router, as well as be able to see the load on the network cards. Maybe there is a program to show usage by user? As well as be able to do packet pritorization.
