Я пытался настроить мост OpenVPN сервер без особого успеха. У меня VPS работает под управлением Ubuntu с одним NIC, который назначил ему статический публичный IP. Я хочу иметь возможность подключить к нему пару клиентов и сформировать сеть, которая будет работать как обычная локальная сеть с работающим вещанием.

Схема физических соединений:Физические сетевые подключения

Я хотел бы иметь laptop и desktop и server в одной сети, скажем, 10.0.0.0/24 . С нижеприведенным конфигом я смог подключиться только к серверу OpenVPN, но между компьютерами нет реальной связи. Самое большее, что я получил, это то, что server может видеть только ARP запросы, поступающие от клиентов, но не отправляет ответ. Я не могу пропинговать server с любого клиента, с любого клиента с server . Я, очевидно, делаю что-то не так, но не могу понять это. Пожалуйста, скажите мне, что где-то есть опечатка.

Я думаю, что в режиме моста OpenVPN не раздает IP-адреса. Таким образом, вам нужно предоставить DHCP-сервер для этого.

Присмотревшись повнимательнее ... вот мои мысли.

Я так понимаю, вы получили tap0 и eth0 соединены с мостом br0? (brctl может проверить)

IP-адрес br0 на сервере НЕ находится в подсети OpenVPN.

Дай угадаю, eth0 - твой интернет-интерфейс. Вам не нужно делать это. Не помещайте eth0 в мост.

Я предполагаю, что вы хотите включить широковещательную передачу, то есть настройку моста, чтобы все VPN-узлы могли передавать друг другу. Я не сделал этого, но все VPN-хосты должны быть в состоянии сделать это без использования eth0 на br0 .

Причина, по которой вам нужен мост на стороне сервера с OpenVPN, заключается в соединении локальной сети и VPN. Если это VPS, это не похоже на то, что позади вас есть локальная сеть, поэтому мост к другому физическому интерфейсу не нужен или что-то для вас сделает.

Я люблю OpenVPN и мой xUbuntu, это БОЛЬШОЙ, чтобы начать первый раз с кривой обучения, и все это - пара вещей, которые могут помочь ...

OpenVPN может выдавать IP-адреса, которые совпадают с сетью вашего сервера, вы не обязаны использовать другой диапазон. Все, что я сделал, это зашел в расширенные настройки DHCP моего маршрутизатора и сказал моему маршрутизатору не выпускать 192.168.1.200 - 192.168.1.250.

Затем я настраиваю свой сервер OpenVPN, чтобы выделить 192.168.1.200 - 192.168.1.250 как пул IP для использования в качестве назначений.

Это сводит к минимуму необходимость в сумасшедших настройках маршрутов и иногда ограничивает их в сетевых коммуникациях [если вы забудете установить маршруты на одном клиенте, его может не увидеть VPN-клиент], но использование тех же IP-адресов, что и ваш маршрутизатор, сохраняет ВСЕ в одном и том же сетевые маршруты и подсеть.

Вот мой /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
# auto eth0
# iface eth0 inet dhcp
#
# The loopback network interface
auto lo
iface lo inet loopback

 auto br1
  iface br1 inet static
  bridge_ports eth0
  address 192.168.1.62
  netmask 255.255.255.0
  gateway 192.168.1.1
  dns-nameservers 208.67.222.222 192.168.1.1
  dns-search home
  dns-domain home

 auto eth0
 iface eth0 inet dhcp

Опция DNS-поиска была хороша, потому что я указал home как домен в моем маршрутизаторе, и теперь, если я перехожу к ping router.home из * nix-клиента, он отвечает, так как это настоящая запись полностью квалифицированного DNS. Это не требуется, чтобы заставить вещи работать, хотя.

Также обратите внимание, что не имеет значения, если вы называете это br0 или br1, у меня были проблемы с настройкой и я перешел с br0 на br1, так как я работал над вещами, как только у меня все заработало, это было на br1, и я не хотел связываться с успехом. :-)

Вот мой серверный конфиг [я удалил точный IP-адрес моего серверного саба, какой бы у вас ни был, и я оставил все заметки и все, в том случае, если это кому-то поможет:

# "dev tun" will create a routed IP tunnel,

# Use "dev tap0" if you are ethernet bridging

# and bridged it with your ethernet interface.
# If you want to control access policies
# over the VPN, you must create firewall
# rules for the the TUN/TAP interface.
# On non-Windows systems, you can give
# an explicit unit number, such as tun0.
# On Windows, use "dev-node" for this.
# On most systems, the VPN will not function
# unless you partially or fully disable

# Configure server mode for ethernet bridging.
# You must first use your OS's bridging capability
# to bridge the TAP interface with the ethernet
# NIC interface.  Then you must manually set the
# IP/netmask on the bridge interface, here we
# assume 10.8.0.4/255.255.255.0.  Finally we
# must set aside an IP range in this subnet
# (start=10.8.0.50 end=10.8.0.100) to allocate
# to connecting clients.  Leave this line commented
# out unless you are ethernet bridging.

# using a DHCP-proxy, where clients talk
# to the OpenVPN server-side DHCP server
# to receive their IP address allocation
# and DNS server addresses.  You must first use

# Note: this mode only works on clients (such as

# Push routes to the client to allow it
# to reach other private subnets behind
# the server.  Remember that these

# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have VPN access,
# use the subdirectory "ccd" for client-specific
# configuration files (see man page for more info).

# EXAMPLE: Suppose the client
# having the certificate common name "Thelonious"
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
;client-config-dir ccd
;route 192.168.40.128 255.255.255.248
# Then create a file ccd/Thelonious with this line:
#   iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN.  This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.

# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
#   ifconfig-push 10.9.0.1 10.9.0.2

# Suppose that you want to enable different
# firewall access policies for different groups
# of clients.  There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
#     group, and firewall the TUN/TAP interface
#     for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
#     modify the firewall in response to access
#     from different clients.  See man
#     page for more info on learn-address script.
;learn-address ./script

# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the VPN, causing
# all IP traffic such as web browsing and
# and DNS lookups to go through the VPN
# (The OpenVPN server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
;push "redirect-gateway def1 bypass-dhcp"

# Certain Windows-specific network settings
# can be pushed to clients, such as DNS
# or WINS server addresses.  CAVEAT:

Вот пример рабочей конфигурации клиента, которую я использую с клиентом Windows 7 pro [Я снова очистил удаленный IP-адрес и порт моего сервера [или вы можете использовать DNS, такой как DynDNS, здесь он работает нормально, если у вас нет статического IP-адреса] Я также продезинфицировал имена моих ключевых файлов также:

# Specify that this is a client
client

# Bridge device setting
dev tap

# Host name and port for the server (default port is 1194)
# note: replace with the correct values your server set up
remote 111.222.333.444 123

# Client does not need to bind to a specific local port
nobind

# Keep trying to resolve the host name of OpenVPN server.
## The windows GUI seems to dislike the following rule. 
##You may need to comment it out.
resolv-retry infinite

# Preserve state across restarts

# SSL/TLS parameters - files created previously
ca ca.crt

key client.key

# Since we specified the tls-auth for server, we need it for the client
# note: 0 = server, 1 = client

# Specify same cipher as server

# Use compression

Могу сказать, что я также использую клиент Android под названием «Настройки OpenVPN» [ОФИЦИАЛЬНЫЙ КЛИЕНТ OPENVPN ДЛЯ ANDROID НЕ МОЖЕТ ПОВТОРЯТЬ НЕ ОБРАЩАТЬСЯ С МОСТОВЫМИ УСТАНОВКАМИ, ВАМ НУЖНО ЗАГРУЗИТЬ УСТРОЙСТВО И УСТАНОВИТЬ Настройки OpenVPN, найденные в Play Store], и Windows и у меня есть пользователь используя клиент OSX, и все очень довольны результатами. Мне понадобилась мостовая установка, так как я использую SWEET Media Server под названием Plex Media Server, который использует широковещательные рассылки для рекламы сервера, и если вы не можете получить широковещательную рассылку, вы не можете использовать клиента [у них также есть удаленная служба, которую они предлагают, но я гайка безопасности и предпочел бы не использовать их безопасное зашифрованное соединение, а вместо этого управлять всем сам.

Надеюсь, все это поможет :-D

Мне потребовалось немало времени и усилий, чтобы придумать все настройки и сделать все счастливым, но это, безусловно, стоило конечного результата.
