I have been using a Dell machine with 2 bce interfaces as a bridge between my LAN and Firewall to shape the traffic. Since after the update, the machine can only run for a few minutes and after that no more connection can go through. Ping from LAN to Internet is OK but when I telnet say to www.yahoo.com at port 80 and issue "GET / HTTP/1.0" I can see the data of different application including the HTML text. For example, I can see uTorrent packets with binaries and also the HTML page being cut short. It's as if, I'm seeing packets jumbled together from different application. I'm using PF to shape the traffic. If I reboot the server, it will panic and I have about 3 different vmcores in /var/crash and not sure what to do with it :( . I've tested the patch to remove stat_IfInFramesL2FilterDiscards but the problem still occurs. As for now, I'm not using the server to shape the traffic because I suspect the driver isn't reliable. I'm going to revert back to the previous driver and hopes its going to work. Sorry if there is not much detail since I'm not sure what to provide. Just tell me what to provide and I'd be happy to do so.
