Hi, I'm relatively new to linux world.I'm just trying to setup a bridge firewall between a router and LAN. I've installed Red Hat Linux 9.0 - 2.4.20-8 from installation CDs and upgraded to 2.4.25 successfully. I've patched my kernel to support bridge firewall also loaded ebtables module,so far so good.Now I tried to create a bridge using the code given in the following link http://www.sjdjweis.com/linux/bridging/bridge I ran the script,and then i typed 'brctl show' to check whether the bridge is up.It showed the created bridge but in the next few seconds machine froze completely.I had to restart the machine.I've tried doing the same thing four to five times but each time it froze after i created the bridge.What's happening??? Do I need to upgrade the kernel with any other patch or am I missing something very obvious. Expecting your reply. Thanks & Regards, S.Rajaraman iDeaLab India Pvt Ltd
