Most clients who use virtual private network

Most clients who use virtual private network (VPN) chose to use hardware firewalls to further increase the security of the internet connection. The firewall router sits between a site and the rest of the network. Firewall allows system administrators to implement a security policy in one centralized place. It is possible to create a VPN without a firewall but it’s not recommended. Because Firewalls are the gateways to secure an internal network and VPN’s are the ways to access internal Networks, It is a common practice that where there’s a VPN implemention, there’s a firewall. This is the case whether it’s a site to site or client to site VPN. A VPN without a firewall basically makes the encrypting features of the VPN useless.
