I'm hoping there's an expert here that is willing and able to help. :) I'm trying to get a Linksys WET11 Wireless Ethernet Bridge (http://www.linksys.com/products/product.asp?prid=432&scid=36) working with a D-Link 530TX+ NIC that uses the rl driver. I have configured the bridge and gotten it to work with a Windows XP box. However I can not get it working on my 4.8 FBSD gateway box. I am trying to set things up so I can use my neighbor's Internet connection as a backup link. He has a Linksys Wireless Access Point/Router in his home. Instead of installing a wireless card in my FBSD box, I bought the WET11 so I could install it by a window to get a better signal. The Linksys bridge connects via ethernet cable to the NIC in my FBSD box. Here's a diagram of the setup: Internet | Public IP | ADSL Modem/Router 192.168.10.1 | dc0 192.168.10.2 | FBSD 4.8 --------- rl0 | 192.168.100.2 dc1 | 192.168.1.2 192.168.100.225 | Wireless Bridge Internal LAN | 192.168.100.1 Neighbor's AP I have added the following to the beginning of my ipfw2 rules to verify that traffic is going out the correct interface: ipfw add allow log ip from any to any via rl0 When attempting a connection to anything on the 100 subnet, I see entries like this in the firewall log: Sep 29 14:58:05 blacksheep /kernel: ipfw: 50 Accept ICMP:8.0 192.168.100.2 192.168.100.1 out via rl0 Sep 29 14:43:47 blacksheep /kernel: ipfw: 50 Accept TCP 192.168.100.2:2626 192.168.100.225:80 out via rl0 However no response comes back. I'm sure ipfw2 is not blocking return packets because I log all denied packets. I have also tried with all ipfw2 rules flushed and have the same result. There may be a clue in the arp tables. After trying connections to the 100 subnet, I have entries like these in the arp tables: ? (192.168.100.1) at (incomplete) on rl0 [ethernet] ? (192.168.100.2) at 00:05:5d:d0:ba:67 on rl0 permanent [ethernet] ? (192.168.100.225) at (incomplete) on rl0 [ethernet] So I thought maybe adding static entries to the arp table might help but it did not. Does anyone have any idea on what I need to do to get this working? I'm willing to read and learn but at this point I'm so stuck I don't know where to turn next. Thanks, Drew
