I assume you are running as root or have made the /dev/bpf[0-3] sufficiently readable by group or by world. are their any tcpdumps running in the background tying up the bpfs? > It's running 2.2.6-RELEASE, and the only network I have is lo0, de0 > and tun0.

I also have tcpdump working fine on > machine's here at work (with fxp and vx devices). did you set the variable in /etc/rc.conf: gateway_enable="YES" or from the command line: sysctl -w net.inet.ip.forwarding=1 (you can check the value from the command line by: sysctl net.inet.ip.forwarding it should reply: net.inet.ip.forwarding: 0 ) did you set the gateway on the Window9x machine to the IP of the FreeBSD machine and also set the netmask correctly? are you using the -alias command on the ppp command line? if you have more problems with tcpdump or the net conection, just yell. --mark.
