hi all, I am using centos3.5 for my firewall home. I would like to do some tests with bridge firewalling. When i try to create the bridge, brctl givtes me this error: br_add_bridge: Package not installed. i find some answers about this error, but the most important is the one that says driver is not loaded into kernel. In my /boot/config-2.4.21-32.0.1.EL file appears compiled as a module, but how can i load it with modprobe?? .... :(( Thanky you -- CL Martinez carlo...

Right now, you can configure most bridge device parameters via sysfs. However, you cannot either: - add or remove bridge interfaces - add or remove physical interfaces from a bridge The attached patch set rectifies this. With this patch set, brctl (theoretically) becomes completely optional, much like ifenslave is now for bonding. (In fact, the idea for this patch, and the syntax used herein, is
