Hi,  
this patch is _not_ meant to provide transparently IP of clients to  
the backends.

It is meant to for nginx to be able to listen on non-local IP, as  
replacement for (eg.) NATing of incomming connections to local port.  
My setups use LVS with direct routing and real-servers without the  
public IPs, using NAT. However the problem I’m facing is IPv6 and one  
option is to use TPROXY sockets to listen to (possibly large number  
of) non-local IPs.

Would you recommend some other solution or is this TPROXY patch fine?

Thanks,  
David
