Bridge network adapters on Linux (ET)
I installed a dual nic card into my Fedora Linux box. I am trying to bridge the two network adapters but i cannot get it working properly. So far it tried the following commands:
su -
brctl addbr br0
brctl addif br0 p1p1 p2p1 (p1p1 and p2p1 are the names of my network adapters)
I also tried the commands on this page but not working either: http://tdistler.com/2011/06/10/netem-wan-emulation-how-to-setup-a-netem-box
I did this a few months back and got it working but cannot remember what i did (should have wrote it down). I think i had to use the dhclient command but dont remember exactly how i used it. Can anyone lend a hand?

ifconfig up is missing.

The linux computer is connected to the internet but my windows pc (the bridged computer) cannot connect. When i do an 'ipconfig' its has an IP address however it cannot connect to the outside internet. Any idea why?
Because your internet provides supplies you with single IP address?
ASKER
Can you explain further? Is there something else i need to do so this will work?
How do you assign IPs to your computers?
ASKER
DHCP
provider's dhcp or your own dhcp server?
ASKER
our own DHCP server.
So you connect it to internet directly? and your provider has other dhcp server in same wire?

Not sure if i understand your question.
Linux box connects to internet through our firewall (DHCP is provided by a local server in our office). My windows PC is connected to 2nd nic on the linux box. Id like to bridge the connection from nic1 (connected to internet) to nic2 (connected to my windows pc).
Reason i'm doing this is i need to run some tests with limited bandwidth and increated latency. Once i setup that bridge i can simulate this.

only missing thing is
ifconfig p1p1 up
ifconfig p2p1 up
ifconfig p1p1 up
ifconfig p2p1 up

nope that didnt help. When i run the dhclient command, should i run it for br0, p1p1(linux to internet), or p2p1 (linux to windows)?
Where you have DHCP server?
To my understanding - you have one at providers, other in your network and now you bridge network.
If you run dhclient on br0 it will get IP from one or from other.

Our network has a static WAN IP (not dynamic IP). Then we have a DHCP server in our network giving out LAN IPs to all the computers in the network.
The linux computer is in my network, geting dhcp from the server. If we run dhclient it would get an IP from our DHCP server.

network bridge does not need IP.
if at all br0 should be the right interface after bridge is configured.
