We are having a very interesting issue with our PIX 525. I have been rebooting my firewall every morning due to a problem getting to anything outside our firewall. I reboot the PIX in the morning and we have Internet all day, but when I come in, in the morning we have no traffic going outside the firewall. It is notable that I have smtp traffic the entire time even when no one can get out from the inside. Anyone have any ideas?
