Fedora Core 4 Firewall and Wireless Configuration

[Robert L Cochran]

I have an HP/Compaq nx9010 laptop with an Broadcom 94306 (rev 02, PCI id 
14E4:4320) wireless chipset. I installed Fedora Core 4 with the firewall 
enabled and SELinux enabled on this and then ndiswrapper 1.2. I used the 
latest Dell Truemobile 1300 Windows driver. Running 'modprobe 
ndiswrapper' yeilds an interface 'wlan0' I can play with. After loading 
the wep key, setting the mode, and setting the essid, I can scan the 
access point but not get an ip address using dhclient with it. It looked 
like a firewall problem. I've opened up ports 67 and 68 on the firewall 
(using system-config-securitylevel and opening both tcp and udp 
protocols.) Still can't get an IP address. My dhcp server is offering an 
IP address in response to the DHCPREQUESTs going out on port 67, it 
looks like the firewall must be blocking the replies. I'm only set up to 
offer ipv4 addresses, but even so I'm wondering if I need to open up 
ports 546 and 547 -- for ipv6? Or could this be an SELinux issue 
affecting ndiswrapper? I don't see any avc denied messages, but perhaps 
they are being logged differently in FC4?

Thanks
