DMIP Application and its Suitable Environments

 

     Introduction:

 Figure 1

  • DMIP is suitable for using when there is no fixed IP address in the server site within the environments of PPP Point to Point Protocol communication agreement and LAN. DMIP provides indirect exchange of the dynamic local IP address to the permanent IP address of FTP/Web server site. The remote client can then access the local GV-series server via IE Browser or Netscape Browseretc.

 Figure 2

Notice:

        1. DMIP is included in the GV-series software. Users do not require to register new ISP.

        2. WWW and FTP Server must be provided. 

        3. Slow connecting speed via permanent IP of FTP Server/Web Server.

        4. Self-maintenance of WWW or FTP Server, and less stable.

Case 1

 Figure 3

  • DMIP provides indirect exchange of the dynamic local IP address of A-PC and B-PC to the permanent IP address of GEO server (FTP/Web) site. The remote client can then access the local GV-series server via IE Browser or Netscape Browseretc. Execute WebCam Server program and set up the IP address of Gateway computer, Video Server Port and Video Output Port. Please refer to the NAT Transfer diagram and Webcam Server Program for set up. 

 Figure 4

        Step 1: Install the software of DMIP in your host computers of GV-series

                      and execute DMIP program.

        Step 2: Key in the desired FTP Login Address [61. 59. 37. 171]

                    Tick on [Default] to apply the default IP address of Proxy server.

                    Key in the desired [user name]

                    Key in the [password]

                    The default Port number is 21 and it can be changed to desired 

                    number.

                    Set up desired [Login path]

                    Tick on [Auto Run] to execute DMIP automatically after power on

                    the PC.

                    After press ok, you will see the status showing successful

                    connection-- [01/06 13:12:26 Success] 

    Step 3: Open IE/ Netscape browser and key in the IP address of Geo-server from the

                   remote PC site

                    (Client), the FTP catalogue image will appear. Click on the desired

                    FTP website, then you      

                    are linked to the desired webcam viewing area.

Case 2

 Figure 10

  • DMIP provides indirect exchange of the dynamic local IP address of A-PC and B-PC to the permanent IP address of  GEO server (FTP/Web) site. The remote client can then access the local GV-series server via IE Browser or Netscape Browseretc. Client's PC, A-PC and B-PC are located within the identical LAN environment. The Browser redirects the signals to the FTP and WWW Geo Server which connect to A-PC and B-PC. Please refer to the NAT transfer diagram and Wbcam Server Program for set up. 

           Step 1: Install the software of DMIP in your host computers of GV-series  

           Step 2: Key in the desired [FTP Login Address]

                       Tick on [Default] to apply the default IP address of Proxy server.

                       Key in the desired [user name]

                       Key in the [password]

                       The default port number is 21 and it can be changed to desired

                       number.

                       Set up desired [Login path]

                       Tick on [Auto Run] to execute DMIP automatically after power on

                       the PC.  

                    After press ok, you will see the status showing successful

                       connection-- [01/06 13:12:26 Success]  

 

            Step 3: Open IE/ Netscape browser and key in the IP address of Geo-server

                  from the remote PC site

                        (Client), the FTP catalogue image will appear. Click on the

                        desired FTP website, then you  

                        are linked to the desired webcam viewing area.

 

  Case 3

 Figur

  • DMIP is not so suitable for using when Client desires to access the GateWay computer within the LAN environment from "outside of the company LAN". The Gateway IP is 210.200.243.252 which has permanent value. Other computers within the company LAN have dynamic IPs. Thus, DMIP is not necessary for using when Client wishes to access the permanent GateWay IP for NAT Transfer. However, it is still possible to use DMIP to connect to GateWay computer by opening up Http Port, Video Server port and Video Output Port. 

 

            Step 1: Enable webcam server

            Step 2: Open IE/ Netscape browser and key in the IP address of

           Geo-server from the remote PC site

            (Client), the FTP catalogue image will appear, then click on the desired

            FTP website, then you  

            are linked to the desired webcam viewing area. 

            Step 3:               

            PC 1

            Set up [IP address] : 192. 168. 0. 20 on net and set 80 as default value

            of [Http Port ] , set 4550 as default 

           value of [Video Server Port] , and  set 5550 as default value of [Video

             Output Port] .

            

            PC 2

            Set up [IP address] : 192. 168. 0. 21 on net and set 81 as default value 

            of [Http Port ] , set 4551 as default 

           value of [Video Server Port] , and  set 5551as default value of [Video 

            Output Port] .  

  • Each PC must have 3 ports available in public for data transfer. In order to control the desired PC, please set up Webcam Server in the Gate Way computer for NAT Translation. (please consult with MIS management team of your company and refer to the following NAT transfer diagram and Webcam Server Program for set up.) 

Figure 12

           NB: HTTP Port, Video Server Port, Video Output Port have been set up in 

                   different PCs and WebCam 

                  Server program is used to remote control different PCs .

Application:

                Users can use IE or Netscape Browser to browse the website. 

                Through the technique of exchanging IP 

                address from dynamic IP of the local GV-series server to the 

                  permanent IP of FTP Server/Web Server, 

                users are allowed to connect to the local host computers.
