I am not allowed to use Nat so i have to create a static routing table..
Ive put a router between with 2 nic's:
Ive seen on various sites that :
Should do the trick but it isnt working for me ... Ipforwarding is enabled.. Also when i use the sys/proc command..
How to make the table? I am using Opensuse 11.2
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
After making an changes (add/modify/delete) to /etc/static.routes, what command should we use to reload the routing table?

Here's my setup.
MODEM -> router (ISP one don't have access)
from the router it split into 2 connection one to my GW (linux debian) and another to a switch which is connected to a web/email server and the gateway.
My gw use x.x.x.27 and x.x.x.26 (everything I use on these ips is ok)
on the web/email server I have x.x.x.28 29 and 30
With this setup it's ok but I want to eliminate the link to the switch and make it pass thru the GW and i can't manage to get it work!
Is there any way to restore back the default ip routing table? For example, my current routing table is something like
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
109.123.95.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 109.123.95.1 0.0.0.0 UG 0 0 0 eth0
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.
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?
In configuring static routing between two different subnets.
I have two different subnets as mentioned below:
I have a linux machine with two NICs on which i would like to configure static routing. details of the NICs are as mentioned below:
I have configured the gateway as 10.77.77.1 on machines which fall under 10.77.77.0/24 subnet and 172.16.40.1 on 172.16.40.0/24 machines.
My main motive here is i want communication to happen between both the subnets.
If the following modifications to route-eth0 and route-eth1.
After 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
My routing table does not get complete for some reason. I'm using a Huawei E220 USB modem on openSUSE 11.3 using NetworkManager to connect.When I connect to the net the routing table looks like

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 eth0
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?
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.

I have a block of 5 static ip's and 2 servers that push HTTP and other services. What is the best method of configuring/routing traffic to individual boxes on the network?
More detail: One of my static IP's is assigned to a dedicated box for an Ubuntu mirror. Another static IP is assigned to a server with all of the HTTP traffic.
Several configurations function to route traffic appropriately (forwarding proxy or 1-to-1 NAT). However, with 1-to-1 NAT, the box is left open to the world with only the software firewall. Do I really need to place a hardware firewall inline to EVERY server?
Or, what other methods of routing and firewall would you recommend?
How to work GNUGK for H.323 Gatekeeper.
I am having a problem, configuring static call routing on GNUGK
In the section
You can see that the routers Local-router1 and 2 has the same dialling plan.
What happens is the gatekeeper send calls randomly to one router or to the other when one of the matching extension is dialled.
What I am trying to do is to force
Any calls coming from Remote1 to go out only throught Local-router1
Remote1 =========================> Local-router1
And any calls from Remote2 to go out throught Local-router2

I have an Ubuntu server running Samba and I would like to share out the cdrom drive to the network. I made a share of the /media directory and it seems to work fine when I insert USB drives and I am able to browse and work with files. However, when I insert a cdrom it automatically mounts to /media/<volume name> and I get a permission denied error when I attempt to access it over the network. I am assuming this is happening because the permissions do not include the execute bit and being a read only file system I can not change this. I made the directory /media/cdrom and manually mounted the cdrom to it and I can successfully access it over the network just like the USB drives. So my question is: Is there a way to make the cdrom automatically mount and unmount to /media/cdrom when I insert and eject disks instead of to /media/<volume name>? Or maybe just have the permissions automatically set so Samba users can open it instead of just see it.

My setup is...I have a wireless access point using laptop as a gateway. The AP is also connected to a switch as is the laptop. So the laptop has two interfaces one wireless and one wired. A third device is using the AP to connect to a server on the internet. The AP sends the packets to my laptop where they are dropped. I've been looking for a solution to this problem without success. Basically is there a way for my laptop to forward all packets it sees from a certain IP address to whatever destination address they have?To clarify, my laptop is just the gateway of the AP and none of the packets are addressed to it at all, it just picks them up using a sniffer or similar tool.

View 4 Replies View RelatedI am having some trouble setting up routing on my Ubuntu 9.10 Server. I have the GUI installed with Webmin and OpenVPN Heres the setup :

1 NIC - ADSL - eth2 - dynamic
What I need to do is the following.
All users are connected to the LAN.
All requests for IP range "146.231.x.x", and "domain.com" need to be routed from LAN (eth1) to WAN (eth0).
All other internet requests need to be routed to ADSL (eth2).
-> I have the masquerading in the linux firewall working for NAT, but all traffic goes to ADSL (eth2).
-> I am using OPEN-VPN over the ADSL also.
-> DHCP and DNS work fine.
I also need all ports opened with the route (from eth1 to eth0)
