An interface apparatus and method facilitates communications on a "connection establishment" type network utilizing the "always connected" type communication techniques thereby eliminating connection establishment steps. The apparatus and method transmits data using the pre-existing "always connected" type application software in the a host computer system's operating system (OS). The interface apparatus intercepts ARP and DHCP service related messages from the host computer's OS and emulates a "always connected" type I/O driver by replying to the service messages with ARP and DHCP service related response messages. As a result, the host computer perceives that the data is being transmitted to another computer system on the same "always connected" type network as the host computer system using a "always connected" type I/O driver. The interface apparatus transmits an ARP message to the host computer's OS which includes an associated address corresponding to a globally unique identification address of the interface apparatus. Perceiving that the associated address is the IP address for its own "always connected" type I/O driver, the host computer system routes the data through the interface apparatus which is then transmitted on the "connection establishment" type network without performing connection establishment steps.
