If I run a steady ping to the firewall, it will always work. If I stop the ping, somwhere along the line (could be hours) it will not be able to reach other servers on my network, or get out to public IP's. Ten to fifteen seconds after I restart the ping to the firewall the box can reach any IP again. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
