OpenVPN clients, allowing access between clients

See I need access between clients and also to set them on a static IP address.


This is achieved by setting up a client configuration directory on your server.
First get the CN from the certificate you created for each client.

 ./build-key client1
Country Name (2 letter code) [UK]:
State or Province Name (full name) [LDN]:
Locality Name (eg, city) [London]:
Organization Name (eg, company) [CNetwork]:
Organizational Unit Name (eg, section) [IT]:
Common Name (eg, your name or your server's hostname) [p1]:
Name [EasyRSA]:pclient1


So the name of your client is pclient1

Create a directory for client configuration e.g.

mkdir /etc/openvpn/ccd

Then set your server config

openvpn.cnf
client-to-client
client-config-dir ccd
push "route 1.2.3.4 255.255.255.0"
route 1.2.3.4 255.255.255.0
 
Then create a file in /etc/openvpn/ccd called pclient1
The contents should be as follows:
iroute 1.2.3.4 255.255.255.0
ifconfig-push 10.30.30.30 255.255.255.0

The above pushes the route for pclient1 (1.2.3.4) into the route table of the kernel and opevpn, and the pclient1 file allocates 10.30.30.30 as the static ip address.
