How should I set up my firewalls?

Most of our customers don't need to make any changes in their firewall settings at all. But if you have a restrictive firewall, you may need to change some settings to let your Palisade network software run.

TL;DR version: On server, give Palisade.exe and lmgrd.exe send/receive privilege; if Automatic Activation fails use Manual Activation instead. On client, give send/receive privilege to PalFlexServer6.exe, PalFlexServer7.exe, or PalFlexServer8.exe depending on your software version.

How should I configure the firewall on my license server?

Your license server does two jobs: it activates your network license with Palisade's license server, and it provides licenses to the client computers.

Internet access (from server only, and only when activating or deactivating a license):

If Automatic Activation of your license fails owing to your firewall, we recommend that you use the Manual Activation procedure rather than make firewall changes. For Manual Activation instructions, see Activating an Activatable License. If you prefer to change server firewall settings and perform Automatic Activation, here is the relevant information:

  • Server Manager makes a direct connection between your server and Palisade’s server via port 80, the same port used by Web browsers for http.
  • If you need to specify exceptions for your server firewall, use *
  • If your firewall won’t let you use wildcards, specify and We do not recommend listing IP addresses in your firewall exceptions, because those could change without notice.

Server's communications with end-user computers (clients):

On the server, it's simplest to list Palisade.exe and lmgrd.exe as exceptions for send and receive.

If you prefer to open specific ports on the server, specify them as described in Port Numbers, and then open those in the server firewall for send and receive.

Client-server communications: Clients and your server must communicate every time a client launches the software, and also periodically while the software is running.

On the client side, the simplest setting is to list PalFlexServer7.exe as an exception for send and receive.

On the server, it’s simplest to list Palisade.exe and lmgrd.exe as exceptions for send and receive.

If you prefer to open specific ports, on the server you need to open the outgoing ports that are listed in Port Numbers. If necessary, open those same port numbers as remote ports in the client’s firewall.
