OT: setting up a bridge

[carlopmart at gmail.com (carlopmart@xxxxxxxxx)]

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
