apache - Wampserver : localhost 403 forbidden after adding allow from all -

i trying make outside access localhost. edited httpd.conf file replacing

allow localhost allow 127.0.0.1 ::1 allow 127.0.0.1 

by

allow 

nothing happenned. however, when tried recover old configuration, nothing works, can't access localhost or 127.0.0.1. '403 forbidden'

my httpd.config:

documentroot "c:/" <directory "c:/wamp/www">     #     # possible values options directive "none", "all",     # or combination of:     #   indexes includes followsymlinks symlinksifownermatch execcgi multiviews     #     # note "multiviews" must named *explicitly* --- "options all"     # doesn't give you.     #     # options directive both complicated , important.  please see     # http://httpd.apache.org/docs/2.4/mod/core.html#options     # more information.     #     options indexes followsymlinks      #     # allowoverride controls directives may placed in .htaccess files.     # can "all", "none", or combination of keywords:     #   allowoverride fileinfo authconfig limit     #     allowoverride      #     # controls can stuff server.     #     # require granted     #   onlineoffline tag - don't remove     allow localhost     allow 127.0.0.1     allow 127.0.0.1 ::1 </directory> 

what can ?

if need share website can create virtual host listening on port 80 (default http):

<virtualhost *:80>    documentroot /var/www/my_web_site   directoryindex index.html    <directory /var/www/my_web_site>         allowoverride none   </directory>  </virtualhost> 

and computer inside lan type ip address.

if want outside of lan should give them public ip address , sure open , forward (from router's settings) port 80 on local ip address.
