Network down after 5 minutes. Only restarting fixes [message #38281]

New install from the quickstart page(s)--made it to the basic operation page and started having network problems. I have tried iptables -F to no avail.

Network goes down about 5 minutes after starting my guest. I had the network up long enough (once) to download a webmin rpm and install it. I even set the root user password and logged in long enough to look at the "Linux Firewall" module of webmin. I was trying to add entries that way and it went down before I could add a rule.

I need ports 3690, 80 and 22 open and everything else blocked. And, of course, I need to be able to access the guest Wink

routing:
0: from all lookup 255
32766: from all lookup main
32767: from all lookup default

netfilter (command from sticky post)
iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Please let me know if I can provide additional information, and thanks in advance!
