May I ask  where traceroute command is? I am using solaris 2.6.  Excuse me
for my ignorance.

 H mm...I get this out of a Linux box.... 

[root at cbl-snicko /root]# traceroute yahoo.com -i eth1 
traceroute: Warning: yahoo.com has multiple addresses; using 204.71.200.245 

[root at cbl-snicko /root]# nslookup yahoo.com 
Server:  rns1.earthlink.net 
Address:  207.217.126.81 

Non-authoritative answer: 
Name:    yahoo.com 
Addresses:  204.71.200.245, 204.71.200.243 

So it looks like it has round robin DNS, but that still doesn't explain the
permission denied. What could control passing ICMP packets besides a proxy
or a firewall?

Can not be round robin DNS. Because it will still just grab the first ip 
of the list and traceroute to it. I can traceroute to it from any other 
box.
