Method for managing a virtual private communication channel between a terminal having a fixed IP address and a server intended to be implemented by a communication device , said communication device being installed on said terminal , said management method comprising: - a detection step (E100) of the availability of a first virtual private communication channel set up between said terminal and said server ; - if said first virtual private communication channel is available and set up: ∘ an obtaining step (E200) of a parameter (PQA) representing quality of transmission by the first virtual private communication channel; and ∘ if this parameter represents a quality of transmission lower than a predetermined quality level: ▪ a closing step (E400) of said first private communication channel set up between said terminal and said server ; ▪ a first recovery step (E500) from said server a set of configuration data required to set up a second virtual private communication channel by the communication device between said terminal and said server , said first recovery step being implemented following a secure communication protocol; and ▪ a setting up step (E600) of a second virtual private communication channel between said terminal and said server using said configuration data. - a detection step (E100) of the availability of a first virtual private communication channel set up between said terminal and said server ; - if said first virtual private communication channel is available and set up: ∘ an obtaining step (E200) of a parameter (PQA) representing quality of transmission by the first virtual private communication channel; and ∘ if this parameter represents a quality of transmission lower than a predetermined quality level: ▪ a closing step (E400) of said first private communication channel set up between said terminal and said server ; ▪ a first recovery step (E500) from said server a set of configuration data required to set up a second virtual private communication channel by the communication device between said terminal and said server , said first recovery step being implemented following a secure communication protocol; and ▪ a setting up step (E600) of a second virtual private communication channel between said terminal and said server using said configuration data. ∘ an obtaining step (E200) of a parameter (PQA) representing quality of transmission by the first virtual private communication channel; and ∘ if this parameter represents a quality of transmission lower than a predetermined quality level: ▪ a closing step (E400) of said first private communication channel set up between said terminal and said server ; ▪ a first recovery step (E500) from said server a set of configuration data required to set up a second virtual private communication channel by the communication device between said terminal and said server , said first recovery step being implemented following a secure communication protocol; and ▪ a setting up step (E600) of a second virtual private communication channel between said terminal and said server using said configuration data. ▪ a closing step (E400) of said first private communication channel set up between said terminal and said server ; ▪ a first recovery step (E500) from said server a set of configuration data required to set up a second virtual private communication channel by the communication device between said terminal and said server , said first recovery step being implemented following a secure communication protocol; and ▪ a setting up step (E600) of a second virtual private communication channel between said terminal and said server using said configuration data. <EOS>
