venet ip question [message #45369]

Hi

I currently have two OpenVZ machines with same configuration.
CT0 has two network devices:
eth0: internal private subnet
eth1: internet

The containers can have internal and/or external IPs.
Access is controlled by iptables in CT0.
I only use IP based venet devices currently.

The problem is I run out of external IPs and want to use the external
IPs of CT0 (eth1) for new containers.

Is this possible? I'm not sure how venet IPs can be routed over eth1
when eth1 has no IP.

You may want to read this relevant doc at the OpenVZ Wiki

http://wiki.openvz.org/Using_NAT_for_VE_with_private_IPs

A similar issue was resolved here using this method, but you may have
to fine tune your run-level scripts to
make this rule persistent across reboots.

YMMV
