Since your results differ from most with the same kernel, have you tested to see if you are behind a transparent proxy at your provider?
No I did not. Is there any tool that can assist in that? Of course I can use tracerout, but how would I know whether any of intermediate hosts was proxy?

This page has some info that might help: http://tracetcp.sourceforge.net/usage_proxy.html but it might require you install that package. Also the tcptraceroute package can help: (slaged this off a google search) Find it at: http://michael.toren.net/code/tcptraceroute/
tcptraceroute servername
will do a TCP traceroute on port 80.
tcptraceroute servername 25
will do a TCP traceroute on port 25 to tell you what hops your TCP packets take to get to the host. Because the ICMP route, and the TCP route might be a bit different because of router configs.
tcptraceroute www.slashdot.org
1 * * * 2 slashdot.org (66.35.250.150) [open] 0.983 ms 0.838 ms 0.347 ms Hmmm, only two hops from me to slashdot? not right, I should at least see the IP's to get to my upstream provider.... Proxy server before I even get to my gateway. -- _____________________________________ John Andersen
