How to make Mobile Device Manager Plus Server use a specific IP Address, if the computer has multiple NICs?

This guide explains how to bind the Mobile Device Manager Plus server to a specific IP address when the host machine has multiple network interface cards (NICs). Admins stop the MDM server, edit wrapper-user.conf to uncomment and set the bindaddress line to the desired IP, delete the following line, make a trivial edit to websettings.conf to save it, then restart the server. Any previously enrolled devices will become unmanaged and must be re-enrolled.

If the machine running Mobile Device Manager(MDM) has multiple Network Interface Cards (NICs) and if you want to restrict the MDM Server communication to a specific IP address, follow the steps below:

  1. Stop your MDM Server.
  2. Navigate to <MDM_Install_Dir>\conf  and open the wrapper-user.conf file.
  3. Remove the # sign before wrapper.java.additional.15=-Dbindaddress="n.n.n.n".
  4. Replace n.n.n.n in the above line with the IP address to which the application has to be bound.
  5. Delete the next line containing wrapper.java.additional.15=.
  6. Open the websettings.conf file located in <MDM_Install_Dir>\conf.
  7. Modify this file(by either pressing the space bar or the Enter key). Save the file now.
  8. Start your MDM server.

Warning! 

If you have already enrolled any devices, they will be unmanaged and you have to re-enroll these devices.

 

Frequently asked questions

What happens to already-enrolled devices after binding the MDM server to a specific IP?

Devices enrolled before the IP binding change will become unmanaged and need to be re-enrolled after the server is restarted with the new binding.

Which configuration file needs to be edited to bind the MDM server to a specific NIC's IP address?

Edit wrapper-user.conf in <MDM_Install_Dir>\conf — uncomment the wrapper.java.additional.15=-Dbindaddress="n.n.n.n" line, replace n.n.n.n with the desired IP address, and delete the next line containing wrapper.java.additional.15= before restarting the server.
