By tproxy you mean transparent proxying as in doing proxy requests from  
nginx while using clients IP?

It is far more simple to use the Real IP module  
[Module ngx\_http\_realip\_module](http://wiki.nginx.org/HttpRealIpModule) ( pretty much all webservers  
(apache -  
mod\_rpaf / lighttpd - mod\_extforward etc) have such modules in one or  
another form ) rather than trying to achieve it on TCP level.

And it is also straight forward to implement it in any other backend  
application.

thanks your feedback.

Yes, we want to get the source-ip directly.  
However, if we want to get real client ip from L7 layer, we need modify  
the  
backend configuration, in some case, we have no permission to modify the  
configuration of Web-server.

Is there other way to get client IP other than x-forward-for/x-real-ip?

thanks  
George
