I have a very basic config on a PIX515E with 6.3(1). Approx. every 10 min I loose connection with the firewall from an inside host and can not get out to the internet or use PDM. The firewall can not ping the inside host. Below is the config.
If I submit the clear arp command I get connection back. Why? Is this something to do with the license which is restricted? Show arp gives me 4 lan addresses on the outside interface and the one host on the inside interface for a total of 5.
