I took the liberty to copy from the following tutorial:  nas-forum

Setup of your CS407

1. ssh login to your CS407
2. ipkg -force-depends install openvpn (provided you have configured optware for your CS407) — link –
3. mkdir /dev/net
4. mknod /dev/net/tun c 10 200
5. mkdir /lib/modules/2.6.15
6. download tun.ko (this is the kernel 2.6 version; to download you will have to register)
7. cp tun.ko /lib/modules/2.6.15/
8. echo 1 > /proc/sys/net/ipv4/ip_forward

If you want to download the sample server/client configuration files, follow below links:

– server –
– client –

Then:

1. cp -R /volume1/public/config /opt/etc/openvpn/
2. cd /opt/etc/openvpn
3. chown -R root openvpn
4. chgrp -R root openvpn
5. chmod -R 755 openvpn

For autostart:

1. cp /opt/etc/openvpn/config/S24openvpn /opt/etc/init.d/
2. chmod 755 /opt/etc/init.d/S24openvpn

Start your VPN Server:

cd /opt/etc/init.d
sh S24openvpn

Download openvpn client

- to be able to reach other private subnets behind the server (CS407)when connecting through VPN add a route on your local clients (e.g. 192.168.1.111): “route ADD  -p 192.168.11.0 MASK 255.255.255.0 192.168.1.7″

[192.168.11.0 - your VPN network] : [192.168.1.7 - your CS407] : [192.168.1.0 - your local network]

==> next step is to create your own PKI, which you will find here
