Few tips to setup the admin section.

OpenVPN hostname/IP setup (you can use NOIP)

Server Network Settings

Routing/Subnets  (allow user to see all other machines on the remote network)

Routing/Subnet OpenVPN AS

Everything else I left as default.

So you install OpenVPN-AS via the tutorial located here –

OpenVPN Acess Server Install Debian + Proxmox

Now when you login to the admin console and click “Start Server” you get the following error:

iptables service not started because of error (SVC_RUN_EXCEPT)

This indicates that the IP tables service isn’t running on your VM. To fix the error carry out the following:

Stop the VM from your proxmox host server:

vzctl stop 101

Make the iptables state and nat modules accessible to containers.

vim /etc/vz/vz.conf

Add “ipt_state iptable_nat” to the end of the list of IPTABLES modules

vim /etc/vz/vz.conf

vz.conf

Allow the container to open the TUN/TAP interface.  These steps specifically affect container ID 101:

vzctl set 101 --devices c:10:200:rw --save

vzctl set 101 --capability net_admin:on --save 

These kernel modules and commands should be ran/installed on the host node before the container is started:

modprobe ipt_mark

modprobe ipt_MARK

modprobe tun

Now start the container:

vzctl start 101

After starting the container run these commands on the host node:

vzctl exec 101 mkdir -p /dev/net

vzctl exec 101 mknod /dev/net/tun c 10 200

vzctl exec 101 chmod 600 /dev/net/tun

Now reboot the host machine, login to OpenVPN admin and start theOpenVPN server. Hopefully all should be working well.

Add a new Debian container within Proxmox. For this tutorial I am using Debian Wheezy.

Shell into the server and run the following to update it:

 
apt-get update 

Then::

 
apt-get upgrade 

Now we install OpenVPN Access Server:

Debian 32 bit:

wget http://swupdate.openvpn.org/as/openvpn-as-1.8.5-Debian6.i386.deb

Debian 6 64 Bit:

wget http://swupdate.openvpn.org/as/openvpn-as-1.8.5-Debian6.amd_64.deb 

To Install, run the following command

32 Bit:

dpkg -i openvpn-as-1.8.5-Debian6.i386.deb

64 Bit:

dpkg -i openvpn-as-1.8.5-Debian6.amd_64.deb

Now lets change the openvpn user password:

 
passwd openvpn 

Now browse to http://xxx.xxx.xxx.xx:943/admin/ (change x’s with your actual IP address)

Login with user: openvpn and the password you set above. This gives you access to the admin panel.

To install the local OpenVPN client browse to http://xxx.xxx.xxx.xx:943 and you should be presented with a download. Simply download the client and run it. You should be prompted with username and password.

PORT FORWARDING

Remember to Port forward 443, 1194 and 943 through to your VM on the router to allow VPN access.
