Once a trigger is occupied, the second or later LAN PC could not use that trigger port until the first LAN PC has

4.10 . Dynamic DNS
For most dial-up ADSL and Cable modem user, it is not easy to get a fixed WAN IP address when
Gate200 connect with the Internet. (whenever SOHO Router’s WAN connection type is PPPoE, DHCP client or
PPTP client, then SOHO Router WAN IP is obtained from ISP side dynamically).
As a result, it is very difficult to host a Web server or FTP server like
