Resolve the IP on some other machine somewhere and ping the IP. If it works, your problem is most likely limited to DNS. If so, most likely you need a rule to let it through. Also if you're using NTP to sync your system times, you will probably need a rule to explicitly allow incoming NTP. On Linux ntpd is what (usually) syncs your time, and it requires that your time servers be able to send packets in to work properly. I mention this mainly because if it's not working, you might not immediately notice, and when it eventually does break you may not connect the failure to this configuration change at that time. -- Derek D.
