Techniques for providing a method and system for TCP to X.25 connectivity are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method, comprising configuring, via at least one processor, an X.25 switch for direct communication with a TCP/IP based network device, configuring, via at least one processor, X.25 packet encapsulation software on the TCP/IP based network device, provisioning, via at least one processor, one or more X.25 PVCs on the X.25 switch, provisioning, via at least one processor, one or more PVCs on the TCP/IP based network device, and routing network traffic directly between the TCP/IP based network device and the X.25 switch.
