I don't know is it make any sense but I've compiled bridge as integrated, not as module. And I don't state any line in "interfaces" file about bridged interfaces; Only br0 exists. Also I'm using br0 as external interface. gw11:/etc# gw11:/etc# cat network/interfaces # /etc/

Hi! I don't think that I could address your problem, but in Debian there is a package called bridge-utils that allows easy bridge creation. One of my systems uses it for a user-mode-linux installation between tap0 and eth2: - auto tap0 iface tap0 inet manual tunctl_user uml-n

I have setup a linux box with a 2.4.19 kernel. I am bridging 2 ethernet devices together using 3Com PCI 3c982 Dual Port cards. (3c59x). What I am seeing is that the module itself uses 30% of CPU to handle just 10mbit both ways (20mbit total). ~6000ps total. From what I have read on the bridge hom
