[Bridge] NFS over bridged interface

[Bridge] NFS over bridged interface

[Vivek Shrivastava]

Hi,
     I am running NFS over my soekris boxes, with eth0 as the primary 
wired interface (that gets dhcp ip address from the server and loads the 
entire NFS filesystem). Now I want to bridge traffic from (some traffic) 
eth0 to eth1 (another interface). But as soon as I add eth0 to the 
bridge, the box stops responding.  I have waited more than 30 sec (the 
default bridging fwd delay), but still see no response. I am a new to 
this community so I am not sure if this has been already discussed. Any 
help will be greatly appreciated.

Thanks
Vivek

You need to use dhcp on the bridge interface.

# brctl addbr br0
# ifconfig eth0 0.0.0.0    # mark up with no address
# ifconfig eth1 0.0.0.0
# brctl setfd br0 0        # turn off forwarding delay
# brctl addif br0 eth0 eth1
# dhclient br0
