Re: question about transparancy

Hmm, I found out that it is not supported for mode tcp:

Starting HAproxy: [WARNING] 111/213701 (5089) : config : 'option forwardfor' ignored for proxy 'load_balanced_smtp' as it requires HTTP mode.

                                                            [  OK  ]

Is this possible for the mode tcp and smtp and Haproxy?
