I have installed Astaro with ICMP forwarding, masquerading, DNS proxy, HTTP proxy, and opened the firewall. Everything works great for about an hour. Then, for no reason, everything fails--I can't even ping the box. There have been several times during the configuration process that I have been "locked out", no pings, nothing. If I go to the firewall box and ping the client, everthing starts working again. What have I done wrong? Is there something I missed in the config?
TIA,
Chris
