My Centos server has two virtual (Openvz) interfaces. One from these interfaces has ipv4 address configured, while the other one has the ipv6 one. In short this server is used for browsing / proxy.
ssh tunnel + tinyproxy = visited web pages detect that client has ipv6 address
OpenVPN (tcp proto) = visited web pages detect that client has ipv4 address
Is it possible to configure OpenVPN (or the OS) like in the first case - to be visible as a ipv6-based host during the browsing?
