You would want to run the batch file on all Multiplicity PCs to ensure the rules are consistent on all PCs.

Changing Multiplicity Ports 

These are the keys you will need to add \ edit. PLEASE back up what you have now prior to changing anything. These are examples are for 64-bit machines.

Primary - controlling other machines

WinKey + R, regedit, enter.  Navigate to the following using the name of the Secondary machine you want to connect to; SDROHAN-TEST is the Secondary MP machine in this example

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Machines\SDROHAN-TEST]

"Name"="SDROHAN-TEST"

"DisplayName"="SDROHAN-TEST"

"DynamicIP"="1"

"Address"="10.8.15.109"

"Passkey"="1101"

"LastWorking"="10.8.15.109"

"Port"="17"

Note the addition of the string value Port=17. You can choose what ever port you like here (excluding the know commonly used ones of course). 

Primary - what itself uses

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security\Ports]

"OverridePort"="1"

"OverridePortPort"="17"

"OverridePortPort2"="55"

OverridePortPort2 is the clipboard port. Again, use any port you like here.

Secondary

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Stardock\Multiplicity2\Security\Ports]

"AllowNonRoute"="1"

"OverridePort"="1"

"OverridePortPort"="17"

"OverridePortPort2"="55"

OverridePortPort2 is the clipboard port. Again, use any port you like here. 

Running a command prompt as admin and netstat -a will show that it is now listening on the new ports
