# "dev tun" will create a routed IP tunnel,
# "dev tap" will create an ethernet tunnel.
# Use "dev tap0" if you are ethernet bridging
# and have precreated a tap0 virtual interface
# 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
# the firewall for the TUN/TAP interface.
# option dev tap
option dev tun
# SSL/TLS root certificate (ca), certificate
# (cert), and private key (key). Each client
# and the server must have their own cert and
# key file. The server and all clients will
# use the same ca file.
#
# See the "easy-rsa" directory for a series
# of scripts for generating RSA certificates
# and private keys. Remember to use
# a unique Common Name for the server
# and each of the client certificates.
#
# Any X509 key management system can be used.
# OpenVPN can also use a PKCS #12 formatted key file
# (see "pkcs12" directive in man page).

# Configure server mode and supply a VPN subnet
# for OpenVPN to draw client addresses from.
# The server will take 10.8.0.1 for itself,
# the rest will be made available to clients.
# Each client will be able to reach the server
# on 10.8.0.1. Comment this line out if you are
# ethernet bridging. See the man page for more info.
option server "10.8.0.0 255.255.255.0"
# Maintain a record of client <-> virtual IP address
# associations in this file. If OpenVPN goes down or
# is restarted, reconnecting clients can be assigned
# the same virtual IP address from the pool that was
# previously assigned.
option ifconfig_pool_persist /tmp/ipp.txt
# 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.
# option server_bridge "10.8.0.4 255.255.255.0 10.8.0.50 10.8.0.100"
# Push routes to the client to allow it
# to reach other private subnets behind
# the server. Remember that these
# private subnets will also need
# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)
# back to the OpenVPN server.
# list push "route 192.168.10.0 255.255.255.0"
# list push "route 192.168.20.0 255.255.255.0"
# 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:
# option client_config_dir /etc/openvpn/ccd
# list 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:
# option client_config_dir /etc/openvpn/ccd
# list route "10.9.0.0 255.255.255.252"
# list route "192.168.100.0 255.255.255.0"
# 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.
# option learn_address /etc/openvpn/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
# the TUN/TAP interface to the internet in
# order for this to work properly).
# CAVEAT: May break client's network config if
# client's local DHCP server packets get routed
# through the tunnel. Solution: make sure
# client's local DHCP server is reachable via
# a more specific route than the default route
# of 0.0.0.0/0.0.0.0.
# list push "redirect-gateway"
# Certain Windows-specific network settings
# can be pushed to clients, such as DNS
# or WINS server addresses. CAVEAT:
# http://openvpn.net/faq.html#dhcpcaveats
# list push "dhcp-option DNS 10.8.0.1"
# list push "dhcp-option WINS 10.8.0.1"
# Uncomment this directive to allow different
# clients to be able to "see" each other.
# By default, clients will only see the server.
# To force clients to only see the server, you
# will also need to appropriately firewall the
# server's TUN/TAP interface.
# option client_to_client 1
# Uncomment this directive if multiple clients
# might connect with the same certificate/key
# files or common names. This is recommended
# only for testing purposes. For production use,
# each client should have its own certificate/key
# pair.
#
# IF YOU HAVE NOT GENERATED INDIVIDUAL
# CERTIFICATE/KEY PAIRS FOR EACH CLIENT,
# EACH HAVING ITS OWN UNIQUE "COMMON NAME",
# UNCOMMENT THIS LINE OUT.
# option duplicate_cn 1
# The keepalive directive causes ping-like
# messages to be sent back and forth over
# the link so that each side knows when
# the other side has gone down.
# Ping every 10 seconds, assume that remote
# peer is down if no ping received during
# a 120 second time period.
option keepalive "10 120"
# For extra security beyond that provided
# by SSL/TLS, create an "HMAC firewall"
# to help block DoS attacks and UDP port flooding.
#
# Generate with:
# openvpn --genkey --secret ta.key
#
# The server and each client must have
# a copy of this key.
# The second parameter should be '0'
# on the server and '1' on the clients.
# This file is secret:
# option tls_auth "/etc/openvpn/ta.key 0"
# For additional privacy, a shared secret key
# can be used for both authentication (as in tls_auth)
# and encryption of the TLS control channel.
#
# Generate a shared secret with:
# openvpn --genkey --secret ta.key
#
# The server and each client must have
# a copy of this key.
#
# tls_auth and tls_crypt should NOT
# be combined, as tls_crypt implies tls_auth.
# Use EITHER tls_crypt, tls_auth, or neither option.
# option tls_crypt "/etc/openvpn/ta.key"
# Set the minimum required TLS protocol version
# for all connections.
#
# Require at least TLS 1.1
# option tls_version_min "1.1"
# Require at least TLS 1.2
# option tls_version_min "1.2"
# Require TLS 1.2, or the highest version supported
# on the system
# option tls_version_min "1.2 'or-highest'"
# OpenVPN versions 2.4 and later will attempt to
# automatically negotiate the most secure cipher
# between the client and server, regardless of a
# configured "option cipher" (see below).
# Automatic negotiation is recommended.
#
# Uncomment this option to disable this behavior,
# and force all OpenVPN peers to use the configured
# cipher option instead (not recommended).
# option ncp_disable
# Select a cryptographic cipher.
# This config item must be copied to
# the client config file as well.
#
# To see all supported ciphers, run:
# openvpn --show-ciphers
#
# Blowfish (default for backwards compatibility,
# but not recommended due to weaknesses):
# option cipher BF-CBC
# AES:
# option cipher AES-128-CBC
# Triple-DES:
# option cipher DES-EDE3-CBC
# Enable compression on the VPN link.
# If you enable it here, you must also
# enable it in the client config file.
#
# Compression is not recommended, as compression and
# encryption in combination can weaken the security
# of the connection.
#
# LZ4 requires OpenVPN 2.4+ client and server
# option compress lz4
# LZO is compatible with most OpenVPN versions
# (set "compress lzo" on 2.4+ clients, and "comp-lzo yes" on older clients)
# option compress lzo
# The maximum number of concurrently connected
# clients we want to allow.
# option max_clients 100
# The persist options will try to avoid
# accessing certain resources on restart
# that may no longer be accessible because
# of the privilege downgrade.
option persist_key 1
option persist_tun 1
option user nobody
# Output a short status file showing
# current connections, truncated
# and rewritten every minute.
option status /tmp/openvpn-status.log
# By default, log messages will go to the syslog (or
# on Windows, if running as a service, they will go to
# the "\Program Files\OpenVPN\log" directory).
# Use log or log-append to override this default.
# "log" will truncate the log file on OpenVPN startup,
# while "log-append" will append to it. Use one
# or the other (but not both).
# option log /tmp/openvpn.log
# option log_append /tmp/openvpn.log
# Set the appropriate level of log
# file verbosity.
#
# 0 is silent, except for fatal errors
# 4 is reasonable for general usage

Subject: [PATCH] openssl: add missing #include statements
Compiling our current master against OpenSSL 1.1 with
-DOPENSSL_API_COMPAT=0x10100000L screams bloody murder. This patch fixes
the errors caused by missing includes. Previous openssl versions would
usually include 'the rest of the world', but they're fixing that. So we
should no longer rely on it.
(And sneaking in alphabetic ordering of the includes while touching them.)
