Hi, Hopefully this will provide some clues. Note that I currently have the server set up as one to one nat. I've tried a bunch of other configurations but this one appears to function as desired. The server has ufw enabled to allow port 80. ## #################################### eric@webserver1:~$ ping google.com ping: unknown host google.com ## #################################### eric@webserver1:~$ ping 173.194.43.38 PING 173.194.43.38 (173.194.43.38) 56(84) bytes of data. < hangs forever here > ## #################################### # i'll try pinging a network printer eric@webserver1:~$ ping 10.0.0.15 PING 10.0.0.15 (10.0.0.15) 56(84) bytes of data. 64 bytes from 10.0.0.15: icmp_req=1 ttl=255 time=0.725 ms 64 bytes from 10.0.0.15: icmp_req=2 ttl=255 time=0.776 ms 64 bytes from 10.0.0.15: icmp_req=3 ttl=255 time=0.759 ms ## #################################### eric@webserver1:/etc$ sudo tail -100 resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 4.4.8.8 nameserver 8.8.8.8 ## #################################### eric@webserver1:/etc/network$ sudo tail -100 interfaces # This file describes the network interfaces available on your system # and how to activate them.

I would post something from the log files but our tiny site is getting slammed by what appears to be automated wordpress attacks. I'm not sure what in this mess would be of use for the apparent dns issue. Thanks in advance for any further tips. - Eric C _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
