I have recently bought myself a physical server and I am trying to create containers which would have their IPs.

The physical machine has both IPv4 and IPv6 addresses. I have accessible another IPv4 and some other IPv6 addresses which I would like to assign to the container. I managed to assign the addresses as follows:

# vzctl set 101 --ipadd 144.76.195.252 --save

I can ping to the machine from the physical machine, but not from the outside world. This also applies to the IPv6 I assigned as well.

This is ifconfig of the physical machine:

eth0      Link encap:Ethernet  HWaddr d4:3d:7e:ec:e0:04
          inet addr:144.76.195.232  Bcast:144.76.195.255  Mask:255.255.255.224
          inet6 addr: 2a01:4f8:200:71e7::2/64 Scope:Global

          RX bytes:1108 (1.0 KiB)  TX bytes:1108 (1.0 KiB)

This is ifconfig of the OpenVZ container:

# ifconfig

venet0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          inet addr:127.0.0.2  P-t-P:127.0.0.2  Bcast:0.0.0.0  Mask:255.255.255.255

          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1

What do I need to do to have the container accessible from the outside world? What could I have forgotten?

Thanks.
