The present invention provides a caption service system for remote speech recognition, which provides caption service for the hearing impaired. This system includes a speaker and a live broadcast equipment at A, a listener-typist and a computer at B, a hearing impaired and a live screen at C, and an automatic speech recognition (ASR) caption server at D. Connect the live broadcast equipment, the computer, the live screen and the ASR caption server with a network. The speaker's audio is sent to the automatic speech recognition (ASR) caption server to be converted into text, which is corrected by the listener-typist, and then the text caption is sent to the live screen of the hearing impaired together with the speaker's video and audio, so that the hearing impaired can see the text caption spoken by the speaker.

The present invention provides a method for NAT traversal in VPN so that the VPN can detect the rule of port allocation for NAT outside the VPN to achieve NAT traversal. The communication structure according to the present invention includes a public network, a client network, a destination network, a first NAT, a second NAT. A DNAT-T proxy server is installed between the first NAT and the second NAT and has the function for the VPN to conduct a plurality of (N times) registrations before sending data out to detect the rule for NAT port allocation of the DNAT-T proxy server, and then inform the next NAT port allocation to the other side of the VPN so as to achieve NAT traversal for the data packets in VPN.
