STUNOptions Property

Server-side STUN options: FINGERPRINT, SOFTWARE, Authentication and the attributes added to Binding Responses.

Syntax

property STUNOptions: TsgcSTUNServer_Options read FSTUNOptions write SetSTUNOptions;

Default Value

—

Remarks

Controls the STUN protocol behaviour of the server:

• Fingerprint: when enabled, adds a FINGERPRINT attribute to every response so that STUN traffic can be multiplexed with other protocols on the same transport address.
• Software: when enabled, advertises the server implementation via the SOFTWARE attribute.
• Authentication: requires the client to authenticate. Enable LongTermCredentials and set its Realm and StaleNonce to activate the long-term credential mechanism (RFC 5389 section 10.2); the actual password for each user is supplied from the OnSTUNRequestAuthorization event.
• BindingAttributes: selects which optional attributes (OTHER-ADDRESS, RESPONSE-ORIGIN, SOURCE-ADDRESS) are added to successful Binding Responses.

Example

oSTUN.STUNOptions.Fingerprint := True;
oSTUN.STUNOptions.Software := True;
oSTUN.STUNOptions.Authentication.Enabled := True;
oSTUN.STUNOptions.Authentication.LongTermCredentials.Enabled := True;
oSTUN.STUNOptions.Authentication.LongTermCredentials.Realm := 'sgc';
oSTUN.Active := True;
