Step 3:  Go to the "Network" tab, find DHCP Reservations block, then click  "+"  to add an entry for your Mac/PC.

b.  How to get the MAC Address:  ""   



Step 5:  Find the Port Settings block (indicated below), then click  "+"  to add ports for your Mac/PC.


Step 6: 

  • Create a Description for this entry.
  • Enter three Ports which should also be set in your Splashtop 2 and Streamer, in both the Public and Private TCP Ports fields.  By default, they should be "6783 6784 6785" as shown below.
  • Insert the IP Address as mentioned for iPv4 Address in Step 4 above, in the Private IP Address field.
  • Save your settings.



Step 7:   Finally, remember to click "Update" to save all the changes.  It will save your settings and restart the router, so your connections will be lost temporarily.

Step 8:  In Splashtop 2, create an entry under Local Mode  by clicking on "Add Computer" on the upper right corner of the computer list, as indicated in the example illustration below.
