I purchased an ASA 5505 a month ago to function as a firewall for our office. The router loses internect connectivity at least two times a day for the past 2 weeks. Inside hosts cannot connect outside, and i cannot even ping the ISP default gateway from the router itself when it is in this state. issuing a reload on the router immediatly fixes the problem. I have also issued a packet trace when it is in this state and it reports that the packet is successfully sent to the default gateway. The default gateway is an Overtur box provided by Timewarner which hands the ASA ethernet. I've replaced the router with a new one, and it is still hapening. Timewarner has checked the overture for errors and it is functioning properly. I'm thinking i have something wrong with the config, so here it is:
