# TAG: option
#       Specifies the location of the PPP options file.
#       By default PPP looks in '/etc/ppp/options'
#
option /etc/ppp/pptpd-options
 
# TAG: logwtmp
#       Use wtmp(5) to record client connections and disconnections.

# TAG: localip
# TAG: remoteip
#
#       IMPORTANT RESTRICTIONS:
#
#       1. No spaces are permitted between commas or within addresses.
#
#       2. If you give more IP addresses than MAX_CONNECTIONS, it will
#          start at the beginning of the list and go until it gets
#          MAX_CONNECTIONS IPs. Others will be ignored.
#
#       3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238,
#          you must type 234-238 if you mean this.
#
#       4. If you give a single localIP, that's ok - all local IPs will
#          be set to the given one. You MUST still give at least one remote
#          IP for each simultaneous client.
#
localip 192.168.0.3

# Network and Routing
 
# If pppd is acting as a server for Microsoft Windows clients, this
# option allows pppd to supply one or two DNS (Domain Name Server)
# addresses to the clients.  The first instance of this option
# specifies the primary DNS address; the second instance (if given)
# specifies the secondary DNS address.
# Attention! This information may not be taken into account by a Windows
# client. See KB311218 in Microsoft's knowledge base for more information.
# Настройка информации о DNS сервере
#ms-dns 10.0.0.1
ms-dns 192.168.0.2
 
# If pppd is acting as a server for Microsoft Windows or "Samba"
# clients, this option allows pppd to supply one or two WINS (Windows
# Internet Name Services) server addresses to the clients.  The first
# instance of this option specifies the primary WINS address; the
# second instance (if given) specifies the secondary WINS address.
#ms-wins 10.0.0.3
#ms-wins 10.0.0.4
 
# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
# system.  This will have the effect of making the peer appear to other
# systems to be on the local ethernet.
# (you do not need this if your PPTP server is responsible for routing
# packets to the clients -- James Cameron)
# Добавляем IP и MAC-адреса клиента в таблицу ARP.
# Таким образом, клиент как бы находится в локальной сети и может подключаться к ее ресурсам

Перезагрузка сервиса

sudo /etc/init.d/pptpd restart

Теперь можно в Windows настроить подключение по протоколу PPTP.
