HELP!!!

Why won't packets foward through the following???:

Code:

[root@agdse2 chris]# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.0009f371fe31       yes             eth1
                                                        ra0

If I assign br0 with an IP address, mandrake can view webpages through it. I'm recieving NO errors from the bridge, yet my DHCP server(on another computer) and any packets for that matter will no reach the computer connecting to ra0! Why?????????? Please help!

Here's some more information:

Damn I need help! I got the bridge to work with conditions. I found out my firewall was blocking all packets, even though I had EVERY port for the TCP/IP protocal open. When I disabled the firewall, the bridge worked. But now I can not see my web pages. It's as if disabling the firewall disabled eth0! When I turn the firewall backon, the bridge stops working and I can see my pages again! WTF! Is the damn firewall broken?! I need help, PLEASE!
