Polynom Server uses port 1337 by default. That can be changed on startup using -p xxxx at the command prompt. It is important to make sure that port 1337 is open in your host firewall and forwards from your router.
A private server is only accessible to a specific group of people, while a public server is accessible to anyone. Polynom Server allows server owners to restrict access by "whitelisting" users. Whitelisting can be used to restrict access to the server to members of a specific organization or enterprise. This can help to protect the server's resources and data from unauthorized access or to conserve resources (i.e., bandwidth).
Server owners in high security environments should mark their server as "Untrusted" and then provide the server's public key to all their users for manual input. This forces the user's clients to verify they are on the right server before connecting. This prevents Man-In-The-Middle (MITM) attacks.
When a server is listed as "Trusted" it means that the client will accept the server's public key (and any changes to it) at face value, and continue to communicate. For most public facing communities this setting is fine, as it would be very resource intensive to try and spoof a server instance.
Server Admins and users with the manage_server permission can add or remove an ID hash from both the whitelist and the blacklist. This change takes place immediately. No restart of servers or clients is required. A user must be whitelisted in order to join a private server. If an ID is blacklisted, they will never be able to access the server again.
If I am a Server Admin or have the manage_roles permission, I can see all the invisible roles. I will always be able to see an invisible role if it has been assigned to me. If I am not a Server Admin or do not have manage_roles, I will see the highest visible role that others have, but I will not see any invisible roles.
Polynom uses the very latest and strongest encryption recommended by NIST and the US NSA's Commercial National Security Algorithm (CNSA) Suite.

Eventually, the CNSA1.0 algorithms will be phased out of Polynom.
