I need run Apache2 on my Debian 7 server. But it run only on tcpv6 port, not on tcpv4 port. I installed it with apt-get install. If I go to localhost or 127.0.0.1 or my server IPv4 address it does not display any website. 

My `/etc/apache2/ports.conf`: 

```
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
 # If you add NameVirtualHost *:443 here, you will also have to change
 # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
 # to <VirtualHost *:443>
 # Server Name Indication for SSL named virtual hosts is currently not
 # supported by MSIE on Windows XP.
 Listen 443
</IfModule>

<IfModule mod_gnutls.c>
 Listen 443
</IfModule>

```

`netstat -plntu`:

```
