Abstract
A method of effective retaining of NAT channel service is provided. The method is applicable to a network system comprising at least one intranet device, a NAT network device and at least one server, in which the NAT network device is allocated with a plurality of NAT channel ports. The intranet device operates a process for detecting a valid period of the NAT channel with respect to the server via the NAT channel ports. The intranet device periodically transmits a packet, within the valid period of the NAT channel, to the server via the NAT channel ports so as to allow each NAT channel to constantly retain active to provide network transmission service.
