Do you have those two devices connected to the same LAN?

If the purpose of this is to demonstrate VMs you just want to bridge the physical interface so that the guest can

bridged networking using VLAN : guest with 2 NIC
hello all,
I have been trying to set-up bridged network with VLAN and not able to
succeed as many tutorials address only single NIC.
I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and
NIC2. following is snippet for guest1
I am not able to get 192.168.0.2 address back on guest eth0.

After a long break, one more try at bond/bridge nics
took a couple months off due to road blocks, hoping a fresh look would
allow me to use my server as desired.
I have three ports, eth0-2 over two nics.
I want to bond them, and then use a bridge to connect to virtual
machines on the virtual host computer.
Never having done this, I am confused on some parts.
Here is where I am at now and any pointers helpful. Single server,
centos 6.x

Cannot Static Routes
Hi,
I'd want to configure persistent static routes, ie in config files, but I
can't configure static routes, I tested:

ADDRESS0=10.10.10.0
NETMASK0=255.255.255.0
GATEWAY0=192.168.1.1
logs says nothing:

Connecting ethX devices directly to a KVM/QEMU guest OS (no bridging)
Hello CentOS gurus, and a belated Happy New Year (or an early Happy
Chinese New Year).
I'm in the process of building a CentOS-6 KVM host machine whose only
function will be to run four independent 'm0n0wall' firewall guest
instances. I have a couple of quad-port Intel NICs to provide four
WAN-side and four LAN-side ports, which will not be shared with any
other guests. Remote

Centos6.4 routing problem
dear All,
I'm facing this routing problem, the setup is actualy part of ltsp, but
I think this problem is Centos-specific.
The server is a Dell Poweredge R210. The install is standard 6.4, updated.
I have one nic facing the public internet:
vi /etc/sysconfig/network-scripts/ifcfg-em1
DEVICE=em1
BOOTPROTO=none
HWADDR=d4:ae:52:c1:28:2b
NM_CONTROLLED=no

2nd NIC troubles
Hi All,
I have 2 NICS in this system. CentOS 6.4
eth0 is the virtual IP from PFSense mapping connected to the router, works
fine.
eth1 is a second NIC that I have assigned a private IP to and connected it
to a switch on the private network. I have many other private devices, so I
know this setup works.
When I connect the cable to the switch and bring up eth1 the system
basically stops taking

Set static IP
Hello,
I want my CentOS 6.5 computer to have a static IP. Currently I get the
IP I want because I have my router assign it on the basis of mac address.
I placed the following file as:

DEVICE="eth0"
BOOTPROTO=static
HWADDR=00:1F:D0:9E:AE:67
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
