Is it possible to use backend server 127.0.0.1 with TProxy?

TProxy does not work in this case:
server local-server 127.0.0.1 source 0.0.0.0 usesrc clientip

I have to delete “usesrc clientip”, but then I can not see “clientip”.

Is it possible to use backend server 127.0.0.1 with TProxy?
Or any other function to make it work with backend server 127.0.0.1?

Please avoid double and cross posting.
