A Virtual Private network can be set up anywhere there is unfiltered web access. If you are in a corporate network or behind a country's firewall (ie. China or Iran), setting up a VPN tunnel could be difficult.

A firewall is a set of related programs,located at a network gateway server,that protects the resources of a private network from users from other network (yhe term also implies the security policy that is used with the programs.) Basically,a firewall,working closely with a router program,examines each network packets to determine whether forward it towards its destination.a firewall also includes or work with a proxy server that makes network request on behalf of workstation users.

Set up a "Home Network"
Contact your network administrator. help you bypass network security.
The administrator can set up a Local Area Network (LAN) behind a firewall in which he can assign whatever IP address block he wishes. The firewall and router will then need to be configured to Network Address Translate (NAT) the 'hidden' internal IP addresses used on the LAN to the one assigned by the ISP when network traffic needs to leave the LAN.
