LapLink has a mechanism for changing the port number used for establishing connections. It is a more cumbersome mechansm than that provided by some other Windows remote control programs, such as Symantec's pcAnywhere, but it is possible to change the port.
LapLink uses UDP and TCP ports 1547 by default. But,
if you edit the LLW.INI file, that will be in the directory
C:\Windows\TSI32\LLW, you can get it to use another port.
In LLW.INI, in the
[TCPIP] section, add
ListenPort= followed by the port
number you wish to use as below:
What makes this approach more cumbersome is that if you need to connect to systems listening on different ports with LapLink, you need to edit the file, save your changes, and then restart LapLink to get it to use the port you want to use. If you want to go back to the default port, you can just put in "1547" for the ListenPort value.
