UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts.
Two UDP sockets are typically used on alternating port addresses to assure that sender and receiver data does not collide or echo back. A UDP Duplex is commonly used for full duplex real-time streaming of UDP data between hosts.

Perform NAT table lookup for this socket.
Used to allow an application to know the original ip:port pair the the client "thinks" it is connecting to. Used mostly to transparently impersonate a remote server/service.
On error, 0.0.0.0:0 is returned and one of the following error codes is set: errServiceUnavailable - if nat is not supported on the current platform or if it was not compiled; errLookupFail - if the nat syscall failed for some reason (extended error code); errSearchErr - if the socket does not have nat information (i.e. is not nated).
NAT lookup is supported on NetFilter for ipv4 and ipv6 (Linux), IPFilter for ipv4 (Solaris, *BSD except OpenBSD, HP-UX, etc.) and Packet Filter for ipv4 and ipv6 (OpenBSD). When using IPFilter or Packet Filter, the first NAT lookup must be performed as root (the NAT device is read only for root and is opened once, unless an error occurs). Permissions on the nat device may be changed to solve this.
