Dyndns et wamp

Bonjours,
Cela fait plusieur jour que je galere... J'essai de faire fonctionné mon Dyndns, mais en vaint, Port 80 ouvert au routeur et au parfeux en TCP et UDP sur l'adresse Ip de mon ordinateur hebergant WampServeur (soit 192.168.1.77). Mon soucis c'est que mon dyndns me redirige vers mon interface NeufBox, je voudrai quelle me redirige vers mon dossier www de wamp...
Mon fichiez Host est modifié :

host:

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
127.0.0.1 localhost
192.168.1.77       http://cybermeca.sytes.net

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost
127.0.0.1       localhost

En esperant avoir été assez clair.
Merci d'une reponse.
