When I try wget URL... I get failed: connection timed out.I have created br0 as a bridge over eth0 to run this VM. The host has this IP 172.30.8.135.The host has access to internet through eth0 and this is the output of route inside the host.
View 1 RepliesWhat exactly does gateway in a route refer to? I know what a default gateway is- it's the route of last resort. But used in context of a host route (with destination specified), what is a gateway and why is it important?
View 5 Replies View RelatedAfter a long time that I didn't touch my PC I just forgot how to configure the routing table I trying to ping the router and get "destination host untraceable" I manually assign the ip of the machine to 192.168.1.2 .And the gateway ip to 192.168.1.1 the only problem now
Is to get to the router interface on 192.168.1.1 to configure my internet and to browse
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
Im having a issue with routing internet traffic from my router two different subnets (vlans).
Theres my setup:-
Server:
Both eth0,1 are running dhcp (two scoopes) that works fine!
The output of route -n is:
I have ip_forwarding on aswell, but i can ping the ip on the server running that dhcp scoope ie ping 192.168.4.1 works great but i just cant get the internet on the clients.
I'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 an Ubuntu 9.10 server installation which have been working flawlessly for some months. The server runs bridged networking, because of some VMs that runs on it. But, a couple of weeks ago the network connectivity have started to disappear now and then (usually once a day or so). Running "sudo /etc/init.d/networking restart" always kicks it back to life.
After a bit of debugging I noticed that when OK the routing table looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default 192.168.1.1 0.0.0.0 UG 100 0 0 br0
While when in the non-working state it looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0

default 192.168.1.1 0.0.0.0 UG 100 0 0 br0
Deleting the two routes to eth0 restores the networking again. Why these "erronous" routes gets added, and what adds them? How to further debug this?

Then i connect to a vpn service and the routing table get's changed..now when i close it, it doesn't reset back to my default routing table.
First, I installed CentOS 5.5 and Quagga 0.99.17.

I added --> #echo "1" > /proc/sys/net/ipv4/ip_forward to forward packet on centos
To be able to use my 3g connection from my laptop I am using Azilink.Azilink work by setting up a little Openvpn server on your smartphone then you connect to your smartphone from your laptop with OpenVPN.From there what i wanted was to use a second VPN connection to an external Linux host and redirecting all my traffic to that tunnel... (redirect-gateway + iptables)It is working but partially..Here is the way I connect through my phone (all steps are I think important for the routing issue...)
1) I plug the phone then a usb0 interface is created with the 192.168.239.5 ip adress (my phone is 192.168.239.4)Then adb connect 192.168.239.4
2) I have to enable a port forward on my phone adb forward tcp:41927 tcp:41927
3) I run the openvpn script (to connect to my phone on wich i have launched Azilink)
So Openvpn connect to 127.0.0.1:41927 (to my phone) From there I have a Initialization Sequence Completed
At this time I am connected through 3G via my smartphone to the Internet..And as you imagine i don't want to enter all the IP adresses of Internet minus RFC1918 manually via route command.I think the problem comes from the fact that when i do the route add default gw 10.8.0.5 it is overwritting all the routes required to establish the first and the second connection am i right? Could someone help me solve that issue ?

I'm trying configure my server for routing between vlans, but I'm having troubles with my server after that vlans are set. I can create vlans and routing is OK, but when I trying remove a vlan, restart the network script or restart the server, the CLI freeze and then I can't do anything. Even Ctrl+C or Ctrl+Z isn't work. I can use other terminal or do other SSH connection (if the network interface used by ssh isn't crashed), but if I try use a ifconfig per example, crash again. The unique solution is restart the server. Nothing about this is found in the log.

WinServer --- (r1)router(r0) --- (eth1)LinuxPC(eth0) --- intranetPC
All netmask is 255.255.255.0
WinServer network is 192.168.1.0/24
intranetPC network is 10.10.0.0/24, gateway is IP of the LinuxPC(eth0): 10.10.0.2
Router:
r1 -IP: 192.168.1.253
r2 -IP: 10.10.0.253
LinuxPC
eth0 -IP: 10.10.0.2
eth1
-IP: 10.10.0.40
-GW: 10.10.0.253
I search in Internet several days to find how to configure the LinuxPC to a gateway. The LinuxPC can ping and connect the WinServer and intranetPC correctly, but the intranetPC cannot ping and connect the WinServer network.
I used the webmin to configure the Gateway.
I used the iptables to set allow all connect, than
iptables -t nat -A POSTROUTING -eth1 -j MASQUERADE
iptables -A FORWARD -i eth0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
In "/etc/sysconfig/network" add "FORWARD_IPV4=true"
