IPv4 to NAT64 redirector
tnat64 provides transparent network access to IPv4 hosts via NAT64 on IPv6-only hosts. tnat64 intercepts the calls applications make to establish TCP connections and transparently proxies them as necessary. This allows existing applications with no IPv6 support to still be able to reach the network with no need in modifications.
