The modem comes up and shows to be online with internet access. When the pfsense box is booting up it hangs on the DNS resolver for a long time. I am unable to access the internet. Is there something I need to reboot or flush out after a modem swap? Any logs that would help diagnose? I put the old modem back on and everything was fine. The entries starting at 18:01:43 are when I plugged the old modem back in and rebooted the pf box.</p>
