PBX in a Flash (PIAF) new system can't connect to eth0

I ordered a pre-built asterisk server (CentOS 6.4), and the company that built it scheduled their only tech support guy for a 3 week vacation as soon as they got it out the door. I know nothing of asterisk except the little I have started reading over the last couple of days, and I know very little linux.

I connected to a network and it showed an IP address on eth0 (obtained via DHCP). I entered that IP into a browser on another PC on the network, and it would not connect. I played around a bit, mostly rebooting and retrying the same thing several times, and eventually got it to connect. I don't know what I did differently (if anything) that made it work. Then when I came back to it the next day, I again cannot connect.

I've tried disabling iptables and fail2ban based on input on a PIAF forum, but this seems to be a linux issue. Using netstat, I can see 4 tcp ports (there are 4 nic cards installed) with local address The IP address that shows up when I run the status command is assigned to a udp port.

If it helps, here is the PIAF status screen:

I started to play with Asterisk some years ago, because my boss was interested in it, then I left the company, so didn't continue and don't know much, but did start to read a good book called Asterisk: the future of Telephony by Jim Van Meggelen. There must be some Asterisk forums around as well.
