Managing Parallels Server Bare Metal Network 144
venet0 Mode
By default, all the Containers on the server are operating in the venet0 mode, which means
that they are connected among themselves and with the server using a virtual network adapter
called venet0. The picture below provides an example of the network structure when all
Containers (Container #1, Container #2, Container #3) are functioning in the
venet0 mode:
Figure 1: Networking - venet0 Mode
All Containers on the server use the venet0 virtual adapter as the default gateway to send and
receive data to/from other networks (shown as the PUBLIC NETWORK in the picture above).
The procedure of handling incoming and outgoing IP packets may be described as follows:
 All IP packets from Containers operating in the venet0 mode come to this adapter and are
redirected through a public IP address of the server to the corresponding server on the public
network.
 All IP packets coming from external networks and destined for Container IP addresses reach
the public IP address of the server first and, afterwards, are sent through venet0 to the IP
addresses of the corresponding Containers.
