Definition
Parameter	Type	Required	Default	Aliases	Comment
name	string	true	-	description, desc	The name used to match this config to existing entries
server_ip4	string	true if no server_ip6	-	server, client_net_ip4	This directive will set up an OpenVPN server which will allocate addresses to clients out of the given network/netmask. The server itself will take the .1 address of the given network for use as the server-side endpoint of the local TUN/TAP interface
server_ip6	string	true if no server_ip4	-	server6, client_net_ip6	This directive will set up an OpenVPN server which will allocate addresses to clients out of the given network/netmask. The server itself will take the next base address (+1) of the given network for use as the server-side endpoint of the local TUN/TAP interface
protocol	string	false	udp	proto	One of: ‘udp’, ‘udp4’, ‘udp6’, ‘tcp’, ‘tcp4’, ‘tcp6’. Use protocol for communicating with remote host.
port	integer	false	1194	local_port, bind_port	Port number to use
address	string	false	-	bind_address, bind, ip	Optional IP address for bind. If specified, OpenVPN will bind to this address only. If unspecified, OpenVPN will bind to all interfaces.
mode	string	false	tun	type	One of: ‘tun’, ‘tap’. Choose the type of tunnel, OSI Layer 3 [tun] is the most common option to route IPv4 or IPv6 traffic, [tap] offers Ethernet 802.3 (OSI Layer 2) connectivity between hosts and is usually combined with a bridge.
topology	string	false	subnet	topo	One of: ‘net30’, ‘p2p’, ‘subnet’. Configure virtual addressing topology when running in –dev tun mode. This directive has no meaning in –dev tap mode, which always uses a subnet topology.
max_connections	integer	false	-	max_conn, max_clients	Specify the maximum number of clients allowed to concurrently connect to this server.
log_level	integer	false	-	verbosity, verb	From 0 to 11. Output verbosity level. 0 = no output, 1-4 = normal, 5 = log packets, 6-11 debug
keepalive_interval	integer	false	-	kai	Ping interval in seconds. 0 to disable keep alive
keepalive_timeout	integer	false	-	kat	Causes OpenVPN to restart after n seconds pass without reception of a ping or other packet from remote.
renegotiate_time	integer	false	-	reneg_time, reneg	Renegotiate data channel key after n seconds (default=3600). When using a one time password, be advised that your connection will automatically drop because your password is not valid anymore. Set to 0 to disable, remember to change your client as well.
auth_token_time	integer	false	-	auth_time, token_time	After successful user/password authentication, the OpenVPN server will with this option generate a temporary authentication token and push that to the client. On the following renegotiations, the OpenVPN client will pass this token instead of the users password. On the server side the server will do the token authentication internally and it will NOT do any additional authentications against configured external user/password authentication mechanisms. When set to 0, the token will never expire, any other value specifies the lifetime in seconds.
certificate	string	true if no ca	-	cert	Certificate to use for this service.
ca	string	true if no certificate	-	certificate_authority, authority	Select a certificate authority when it differs from the attached certificate.
crl	string	false	-	certificate_revocation_list, revocation_list	Select a certificate revocation list to use for this service.
key	string	false	-	tls_key, tls_static_key	Add an additional layer of HMAC authentication on top of the TLS control channel to mitigate DoS attacks and attacks on the TLS stack. The prefixed mode determines if this measurement is only used for authentication (–tls-auth) or includes encryption (–tls-crypt).

network_remote	list	false	-	remote, net_remote, route	Remote networks for the server, add route to routing table after connection is established
data_ciphers	list	false	-	ciphers	One or multiple of: ‘AES-256-GCM’, ‘AES-128-GCM’, ‘CHACHA20-POLY1305’. Restrict the allowed ciphers to be negotiated to the ciphers in this list.
data_cipher_fallback	string	false	-	cipher_fallback	One of: ‘AES-256-GCM’, ‘AES-128-GCM’, ‘CHACHA20-POLY1305’. Configure a cipher that is used to fall back to if we could not determine which cipher the peer is willing to use. This option should only be needed to connect to peers that are running OpenVPN 2.3 or older versions, and have been configured with –enable-small (typically used on routers or other embedded devices).
auth_mode	list	false	-	authentication_mode, auth_source	Select authentication methods to use, leave empty if no challenge response authentication is needed.

cert_depth	integer	false	-	certificate_depth	From 1 to 5. When a certificate-based client logs in, do not accept certificates below this depth. Useful for denying certificates made with intermediate CAs generated from the same CA as the server.
register_dns	boolean	false	false	-	Run ipconfig /flushdns and ipconfig /registerdns on connection initiation. This is known to kick Windows into recognizing pushed DNS servers.
ocsp	boolean	false	false	use_ocsp, verify_ocsp	When the CA used supplies an authorityInfoAccess OCSP URI extension, it will be used to validate the client certificate.
user_as_cn	boolean	false	false	username_as_cn	Use the authenticated username as the common-name, rather than the common-name from the client certificate.
user_cn_strict	boolean	false	false	username_cn_strict	When authenticating users, enforce a match between the Common Name of the client certificate and the username given at login.
mss_fix	boolean	false	false	mss	Announce to TCP sessions running over the tunnel that they should limit their send packet sizes such that after OpenVPN has encapsulated them, the resulting UDP packet size that OpenVPN sends to its peer will not exceed the recommended size.
reload	boolean	false	true	-	If the running config should be reloaded on change - this may take some time. For mass-managing items you might want to reload it ‘manually’ after all changes are done => using the ansibleguy.opnsense.reload module.

The instance description/name is used to match your config to the existing entries.

WARNING: The openvpn_server and openvpn_client module share the same namespace! Be aware that you p.e. CANNOT create an openvpn_server with the same name as an existing openvpn_client (on the same box)!

Use can create an manage certificates using the OPNSense WebUI!
