http://askubuntu.com – I've got an Ubuntu 10.04 server with this configuration: eth0: 192.168.10.XXX mask 255.255.255.0 gw 192.168.10.254 eth1: 192.168.0.XXX mask 255.255.255.0 gw 192.168.0.3 eth0 is used for incoming and outgoing trafic (internal webserver) eth1 i want to use for accessing the network: 192.168.51.0/24 by gateway 192.168.0.1 when eth1 is down, the webserver is reachable. When i want to bring the state of eth1 to up, i use the following commands: $ sudo su # ifconfig eth1 up # route add -net 192.168.51.0 netmask 255.255.255.0 gw 192.168.0.1 # ping 192.168.51.XXX [i've got contact] # ip route ad (HowTos)

Setting Gateway In Linux 8 weeks 14 hours ago

i am having Ubuntu box with two nic,eth0:for private and eth1 for public with static ip assigned.

on eth0:192.168.30.1 eth1:x.x.106.111

I want to set this box as Default gateway for all the other machines and wan to do NAT ing on it.

But after assigning Ip address in eth1 i am not able to ping 192.168.30.0 network and Public Ips.

route

default x.x.106.1 iface eth1

x.x.106.0 * 255.255.255.

I have an UBUNTU server VM installation with two NICs. eth0 is on the LAN network, configured by DHCP and is working fine. I manually configured eth1 with a static IP on the DMZ network but can't ping it, I think this might be a routing issue but I'm new to this so any help would be appreciated!

i have a dedicated server, with "Virtuozzo" on it running VPS's.

I have: eth0 - which is configured to the internal network, that one is fine.

Now I have: eth1 - which has two ranges routed through this device.

x.x.134.x (which has 12 IP's sequentially) x.x.132.x (which has 5)

eth1:

DEVICE="eth1" HWADDR="00:25:90:37:65:67" NM_CONTROLLED="yes" ONBOOT="yes" IPADDR="x.x.134.x" NETMASK="255.255.

I have a machine working like gateway and have two network interfaces:

eth0 LAN : 192.168.1.0/24 eth1 WAN : XXX.XXX.XXX.XXX (my public ip)

This machine has 3 VM guest over virtualbox.

Hi All,

I have 2 NICs in my U9.04 Server box (eth0, eth1). After I added 2 virtual interfaces for each physical interface (eth0:1,eth0:2,eth1:1,eth1:2), the MAC addresses of all the interfaces have changed to that of eth0. Because eth1 was configured to be on my local network, I can't access the box remotely anymore.

I've got an issue with a VMWare server running RHEL 6.3 that has dual E1000 NICs. I have configured the cards as I would normally do in /etc/sysconfig/network-scripts as ifcfg-eth0 and ifcfg-eth1.

I have some problems connecting a Playstation to my VPN via another PC.

Hardware: PC that should route incoming traffic from the Playstation to VPN: eth0 - connected to the internet eth1 - connected with my Playstation.

I can't ifdown an interface on a Debian 6.0.5 box;

user@box:/etc/network$ sudo ifdown eth0 && sudo ifup eth0 ifdown: interface eth0 not configured SIOCADDRT: File exists Failed to bring up eth0.

user@box:/etc/network$ cat interfaces auto lo iface lo inet loopback

allow-hotplug eth0 allow-hotplug eth1

auto eth0 iface eth0 inet static address 10.0.0.1 netmask 255.255.255.0 gateway 10.

Hi guys,I have two network interfaces, say eth0 and eth1, where eth0 uses dhcp and eth1 has a static IP. When I ifdown eth1 and ifup eth1, the internet access from eth0 just becomes not... [by zeonjeng]
