==== Subnet Addressing ====
The server and client should not have identical LAN subnets, e.g. 

VPN Server could have a 192.168.2.0/255.255.255.0 

VPN Client could have 192.168.3.0/255.255.255.0 

This applies for all routers/switches/firewalls in the VPN circuit

==== Port Forward ====

Your firewall/router needs to be configured to forward the correct port. The default port to forward is **1194**. Forward this to your Gargoyle router WAN port. You might need to read your router manual on how to do this.

==== Dynamic DNS Service ====

If you don't have a fixed IP from your ISP you will need to set-up a Dynamic DNS Services. see [[dynamic_dns_services|Dynamic DNS Services]]

==== OpenVPN server ====

Set-up the server
