Hi everyone,
I'm trying to understand if the DNS problem I'm having is my fault or my
ISP's fault.
>From the server, I try to get to three different locations:
emmajane at xtrinsic:~$ traceroute 207.218.245.47
traceroute to 207.218.245.47 (207.218.245.47), 30 hops max, 38 byte packets

But from my client's computer, the traceroute fails:
Tracing route to emmajane.net [66.98.212.88] over a maximum of 30 hops:

If I try from my server to get to #12, I fail as well:
emmajane at xtrinsic:~$ traceroute 64.245.101.10
traceroute to 64.245.101.10 (64.245.101.10), 30 hops max, 38 byte packets

4 * * *
So where does the problem lie? My ISP is trying to tell me that I have a firewall
installed on the server. I've done a plain debian install which does NOT include
a firewall. My ISP is refusing to help because I have debian installed. I'm pretty
sure it's not actually my fault though....
Any thoughts would be much appreciated!!
