Abstract
A method for control of a soft generic routing encapsulation (GRE) tunnel based on client activity includes: receiving a data packet from a first external; storing an identifier associated with the first external device in a client table and a corresponding timestamp associated with receipt of the data packet; creating a soft GRE tunnel between a local interface of the computing device and a remote gateway; updating the client table, wherein updating the client table includes adding a new identifier and corresponding timestamp associated with additional external devices upon receipt of respective data packets, and updating the timestamp corresponding to the respective identifier upon receipt of an additional packet from an additional external device; and halting a GRE health-check process associated with the soft GRE tunnel once a predetermined period of time has elapsed since the timestamp corresponding to each identifier stored in the client table.
