=== Description ===
[http://openvpn.net OpenVPN] is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, fail-over, and fine-grained access-controls. Starting with the fundamental premise that complexity is the enemy of security, OpenVPN offers a cost-effective, lightweight alternative to other VPN technologies that is well-targeted for the SME and enterprise markets.

This contrib will help you configuring OpenVPN in routed mode. With this mode, clients connecting to the VPN from the outside will get an IP in a virtual private network. (this network will use a separated IP range from your standard local network, unlike the [[OpenVPN_Bridge]] contrib
This contrib will help you configuring '''OpenVPN in routed mode'''. With this mode, clients connecting to the VPN from the outside will get an IP in a virtual private network. (this network will use a '''separated IP range''' from your standard local network, unlike the [[OpenVPN_Bridge]] contrib

=== Installation ===
<tabs container><tab name="For SME 10">
/!\ new default cipher = AES-128-GCM and HMAC SHA256, if you have issues check the configuration options
yum install smeserver-openvpn-routed --enablerepo=smecontribs
if you have smeserver-openvpn-bridge installed and configured then all will work automaticly.
It will change its port to a different one, and it will copy certificates from the bridge openvpn
to know the new port
config getprop openvpn-routed UDPPort
</tab>
<tab name="For SME 9">
install fws repo, see : [[Fws]]
install fws repo, see : [[Fws]]
yum install smeserver-openvpn-routed --enablerepo=fws,smecontribs
yum install smeserver-openvpn-routed --enablerepo=fws,smecontribs
you will then have to configure by hand
This contribs is really minimal and doesn't have a panel to configure everything. You have to configure all by hand.
If you already run the [[OpenVPN_Bridge]] contrib, you can just copy all the certificates:
cp -a /etc/openvpn/bridge/{priv,pub} /etc/openvpn/routed/
</tab>
</tabs>
=== Configure ===
This contribs is really minimal and doesn't have a panel to configure everything. You have to configure all by hand. Except on SME10 if you already have smeserver-openvpn-bridge installed and configured.
here's the file the contrib expects to see before being started:
here's the file the contrib expects to see before being started:
* /etc/openvpn/routed/priv/takey.pem (an optional shared key)
* /etc/openvpn/routed/priv/takey.pem (an optional shared key)
If you already run the [[OpenVPN_Bridge]] contrib, you can just copy all the certificates:
and an available port to bind to.
==== Using PHPki ====
If you are using the PHPki contrib to manage your certificates you need to do the following :
Create a new certificate for your OpenVPN server - make sure it is a VPN server only certificate.
{{Note box|Make sure you don't protect the private key with a password}}
From PHPki get the following certificates :
From the main page of PHPki :
dh pub/dh.pem - Download the Diffie-Hellman parameters
ca pub/cacert.pem - Download the Root Certificate
If you need to, get a copy of the revocation list
crl-verify pub/cacrl.pem - Download the Certificate Revocation List
The Revocation certificate can be obtained automatically with a cronjob
db configuration setprop openvpn-routed CrlUrl 'https://your-phpki-box.domain.net/phpki/index.php?stage=dl_crl_pem'
From the Manage Certificates page of PHPki :
cert pub/cert.pem - use the PEM Certificate
key priv/key.pem - use the PEM Key
Copy them to the relevant directories as above
Make sure that the certs are set 0600
If you want your VPN clients to use the SME as default gateway for all traffic once connected :
db configuration setprop openvpn-routed RedirectGateway enabled
signal-event openvpn-routed-update
You can now add your Client certificates to your device.
Make sure you have a user on the server.
Make sure in your device that you choose Certificate + Password as an option.
Enter in your user name and password in addition to the certificates

you can also set the property PushRoute to disabled to any network in networks db to avoid the contrib to push the network to the client
===Workarounds and known issues===
if you migrate from SME8 to SME9 and are not able to connect after correctly migrating your certificates, this might be related to not secure enough algorithm. CentOS 6.9 release notes state that "Support for insecure cryptographic protocols and algorithms has been dropped. This affects usage of MD5, SHA0, RC4 and DH parameters shorter than 1024 bits." Of course real solution would be to migrate all your certs to better algorithm.
workaround :<syntaxhighlight lang="bash">
echo -e "LegacySigningMDs md2 md5\nMinimumDHBits 512\n" >> /etc/pki/tls/legacy-settings
service openvpn-routed restart
</syntaxhighlight>
