I've tried how different switches at different locations (home and work) which just happened to have different cables. 8-) The funny thing is that the version of this card that lacks a modem seems to work just fine. Windows can also talk to the card that is having problems under FreeBSD without any difficulty. -- Justin To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

For curiosity's sake, I'd try a different cable to the hub...

I was using this same card, sans the modem on my laptop for a while earlier in the week and it was fine. I didn't try the ping it from a remote location, however. I'll have to try that tonight.

IP wierdness...
After the recent introduction of cardbus support into -current, I decided to upgrade my laptop. At first glance, the system seemed to support a Xircom "Real Port" 10/100/56K modem card with the dc driver. The funny thing though is that, although I can initiate IP or TCP connections to remote hosts, the system seems to drop all incoming connections. This even applies to ICMP traffic. For instance, a 4.1-stable machine can not ping my laptop, but the laptop can ping/telnet/ftp to the 4.1-stable machine. Looking at tcpdump traces on the laptop, it appears that the ICMP echo request is received correctly, but the system never responds. I'm not running IPSEC or ipfw, and all of the sysctls that seem to be related to filtering or rate limiting incoming packets look normal. I'm running -current as of a few hours ago, but this has been broken for me for at least a week in -current. -- Justin To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
