Abstract: A system and method are disclosed for making Virtual Private Network (VPN) connections in networks, which currently cannot have VPNs due to technical limitations and some practices by network operators. The system and method are a solution that may be independent of VPN protocols used for making secure connections. The system and method can be used in a public cloud on the internet or a in a private network. The system and method are capable of providing VPN connections “everywhere” and in all connection scenarios.
Abstract: A system and method to estimate and to limit usage time of network applications by a centrally located router is provided. The router first modifies the Domain Name System (DNS) protocol's Time To Live (TTL) values to a fix value, then it counts the number of DNS queries for an application. Number of queries multiplied by the fixed TTL value gives estimated duration of the application.
