I have two servers linked together through a virtual link (actually a 4in6 tunnel). One is an OpenVZ VPS server which has an unused IPv4 address configured on a venet interface (cannot be bridged), and I want to transfer this IPv4 to the other server.
In other words, I want to link two interfaces together:
- all IPv4 traffic coming from the venet0 interface (the spare IPv4) should be forwarded to the ip6tnl1 interface
- all IPv4 traffic coming back from the ip6tnl1 interface should be forwarded to venet0
Do you know how I can set up this, keeping in mind that venet interfaces cannot be bridged?
