I won't try to tell you how to fix your problem, but I'll tell you what works for me on COMCAST cable with FreeBSD. Maybe it'll give you some ideas. FIREWALL/BRIDGE: I got a junker 486/66 (16 or 20 MB) with no hard disk and put two ISA NICs in it. On my desktop FreeBSD, I read the "picobsd" manpage and built a picobsd firewall+bridge floppy and use it to boot the 486. The system goes between the cable modem and acts like a cable, with no IP config, etc. It shouldn't be real hard to make a router version, but the bridge version avoids problems with DHCP, NAT, etc. DESKTOP: On my desktop, I wrote a Python program hooked into a fvwm2 button to control and monitor my online status. It uses: ifcommand = "/sbin/ifconfig de0 " upcommand = "/sbin/dhclient de0" downcommand = ifcommand + "down delete; kill `cat /var/run/dhclient.pid`" I think I've conneted from a console using just: /sbin/dhclient de0 The only thing in my /etc/rc.conf is to turn on the desktop's firewall. You might review your kernel config. And list your current firewall settings (ipfw -show) to ensure it's OK. I did not not have to give my MAC to COMCAST, but they might or might not have locked in on the first one they found; I've never switched. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

The company I work for had a customer using a Comcast business account that had to jump thru hoops to get everything working properly. One of the things was, IIRC, registering the MAC. I also remember Comcast insisted on firewalling the IP space themselves. The customer had to call Comcast to open not only outbound ports but _inbound_ ports, as well! Of course, Comcast charged a setup fee for this "service" AND a monthly "maintenance" fee. Hope this isn't the case for you, Steve ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Here's another possibility: My cable company (in the UK) requires customers to register the MAC (ethernet) address of your NIC before you're able to get an IP from them using DHCP. Don't know if comcast is the same, but it's a possibility.

What error messages can you find in /var/log/messages and or /var/log/dmesg.boot? What else (if anything) is in rc.conf? Does ep0 show up in dmesg(8)? What is the output of ifconfig(8)? Can you assign an address with ifconfig(8)? Have you tried dhclient(8)? Maybe with the -v switch, might give us some meaningful error messages.
