Can you post output of
# ip r s 83.170.73.232
command on HN.

Also you say, that you can't reach VE from world. Can you ping VE from HN? Can you ping VE from your NET? Can VE ping HN, other servers?

Thanks.

root@server30444 [/etc/vz]# ip r s 83.170.73.232
83.170.73.232 dev venet0 scope link src 83.170.73.235
root@server30444 [/etc/vz]#

from VE:

-bash-3.00# ping google.com
ping: unknown host google.com
-bash-3.00# ping localhost
PING localhost.localdomain (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=0 ttl=64 time=0.030 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=64 time=0.023 ms

how can I try to ping VE from HN? Razz

When I enter 83.170.73.232 ip, its try to connect to HN, not to VE.

you can ping by name (google.com) only if nameserver for VE is set. Have you done it? (vzctl set <veid> --hostname your.dns.server)

Hi
I have the same problem. As I understood the problem is that there is no default gw after VPS starts.

After some experements found that command "ip route add ..." which is used in "/etc/sysconfig/network-scripts/ifup-routes" isn't work.

-bash-3.1# ip route add 191.255.255.0/24 dev venet0 scope host
RTNETLINK answers: Operation not permitted

This is strange because command "route add" works fine.

I modify script ifup-routes to use this command and all start work.

But I think that there is other way to solve this problem. Smile
