I'm running 1.0.1 from the ISO release, with miniupnpd (20070208) and squid (2.6.5_1-p15). I'm having problems with pfSense not staying connected to Comcast. It's a DHCP renewal issue, I think. If I reboot my cable modem or there is as interruption on Comcast's side, pfSense will not automatically renew my IP, it still shows an old address and interface status of 'up'. I have to manually renew.
Also, today, Comcast somehow lost my modem in their system, so their captive portal was sending me to the new customer site with info on how to activate my service. After they fixed this, HTTP requests started working, HTTPS, POP3, and my SIP phone were not working. A manual renew didn't fix this, I had to reboot the router, then everything started working. This is probably not a DHCP issue, but I don't know how to troubleshoot this one, especially because I won't be able to recreate it unless Comcast has problems with my account again.
