To: freebsd-isp@freebsd.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi, I've setup a bridge on a freebsd machine with 2 network cards, according the following document (except i just have one pass all rule in the ipfw, for testing purposes): http://people.freebsd.org/~nsayer/bdg-ipfw.txt . I plugged a computer (10Mbps nic) into one of the interfaces (100Mbps) with a crossover cable, and the other interface (100Mbps) of the bridge into the network. When i try to ping another machine from the network from the box behind the bridge, i don't get any replies. Occasionally though, the packets do get thru and i get a few replies (around 99% packet loss). I ran tcpdump on the bridge to see what can be wrong. Here's the line that caught my attention: 20:27:33.722272 truncated-ip - 38 bytes missing!10.10.9.111 > 10.10.8.24: icmp: echo request (DF) Same happens if i try to access a webserver or do other things, it loses a different amount of bytes every time though. Has anyone else had this problem before? Can this be happening because the machine behind the bridge has a 10Mbit nic while the bridge has 100Mbit cards? Any help is greatly appreciated Regards, Anthony Volodkin __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
