I have a PPTP VPN service on a Ubuntu server, and when I connect to it, I found I cannot connect to some web site, e.g.

I tried to ping the web site, but failed. So I tried tracert on windows, and below is the output.

Tracing route to [] over a maximum of 30 hops:

    1   784 ms   626 ms   821 ms
    2   513 ms   631 ms   964 ms []
    3   493 ms   483 ms     * []
    4   575 ms   496 ms   401 ms []
    5   434 ms   379 ms   467 ms []
    6   592 ms   584 ms   941 ms []
    7   540 ms   528 ms   477 ms []
    8   561 ms   695 ms   542 ms []
->  9   514 ms   800 ms   632 ms
    10     *        *        *     Request timed out.

The 9th record is very interesting, it does not seem to be a valid public internet address.

I have no idea how to troubleshoot this kind of network problem. I hope some can help me here.

thanks, David

I'm not sure what the title has to do with the question. Your issue occurs on the 10th hop, why do you need more? – MDMarra Jun 30 '10 at 15:34

See this link

Scroll down to TRACERT Synatax to configure more than the 30 default hops in the command.

I have never had a Microsoft link break. – Moab Feb 29 at 21:10
I have - there are boatloads of broken TechNet links on MS blogs. KB's probably are good, but it wouldn't hurt to include a sample command in the answer. – Ben N Feb 29 at 21:13
Mine is not a tecknet link. Fee free to edit my answer. – Moab Feb 29 at 22:48
