Scott,

We are not blocking anything. I can ping the other ip's but the 5.
block dies. I logged into our upstream provider AT&T and did a
trace route from their backbone and it seems to die at omantel.
The connection before omantel is cogent communications.

Here is the traceroute for your information:
