Hi there, Hopefully somebody can help me with how to diagnose this problem.
I recently switched to Comcast, and I have been running great with them for a few weeks. They supplied me with a Ubee cablemodem, and last week I bought a Motorola SB6120 to replace it. Shouldn't have done that! The modem itself seems to work fine ... if I plug my Windows PC straight into it, it gets an address via DHCP and everything is fine. If I plug pfSense into it however, it never gets an address (it tries the cached one which is no good with Comcast), and the interface goes up and down every so often ... presumably because of the pinger script. Comcast, unsurprisingly, are not helpful :-( The hardware I'm running pfSense on is one of the new SuperMicro X7SPA-H boards. It worked great with the Ubee modem. The pfSense I am currently running on it is: pfSense-2.0-BETA1-20100407-1435 In the system log I see this: Apr 17 14:19:14 firewall kernel: em1: link state changed to UP Apr 17 14:19:15 firewall dhclient: netstat Apr 17 14:19:15 firewall dhclient: PREINIT Apr 17 14:19:15 firewall dhclient[25679]: DHCPREQUEST on em1 to 255.255.255.255 port 67 Apr 17 14:19:16 firewall dhclient[25679]: DHCPREQUEST on em1 to 255.255.255.255 port 67 Apr 17 14:19:18 firewall dhclient[25679]: DHCPREQUEST on em1 to 255.255.255.255 port 67 Apr 17 14:19:22 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 1 Apr 17 14:19:22 firewall check_reload_status: rc.linkup starting Apr 17 14:19:26 firewall last message repeated 4 times Apr 17 14:19:27 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 2 Apr 17 14:19:35 firewall last message repeated 4 times Apr 17 14:19:37 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 5 Apr 17 14:19:42 firewall sshd[50919]: Accepted keyboard-interactive/pam for root from 10.10.10.10 port 52603 ssh2 Apr 17 14:19:42 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 9 Apr 17 14:19:51 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 14 Apr 17 14:20:05 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 8 Apr 17 14:20:13 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 8 Apr 17 14:20:21 firewall dhclient[25679]: DHCPDISCOVER on em1 to 255.255.255.255 port 67 interval 2 Apr 17 14:20:23 firewall dhclient[25679]: No DHCPOFFERS received.

I guess one thing I should try is to install on some other HW to see if it's a Comcast/FreeBSD issue, or maybe the 1.2.3 release and see if the problem happens there too.
