Here is the problem:

# vzctl enter 1000
entered into VPS 1000
-bash-3.00# traceroute 69.64.46.7
traceroute to 69.64.46.7 (69.64.46.7), 30 hops max, 38 byte packets
1 203.171.31.140 (203.171.31.140) 0.069 ms 0.032 ms 0.026 ms
2 203.171.31.140 (203.171.31.140) 0.030 ms !<10> 0.030 ms !<10> 0.026 ms !<10>
-bash-3.00#

VPS cannot estabilish connectivity to the net. Seems packets never leave the HN. (203.171.31.140 is the IP of the HN)
Here are the details:

moderator, you can delte this thread, its kinda silly..

Please don't do that.
Vass asked me to write up the network diagnostics script in the wiki. Did the script help you see the problem? I need some feedback to get motivated ...
