2.2.3.4.6 ServerFlags

The ServerFlags value specifies several configuration settings for the RRAS server implementation. It MUST be defined under the following registry key.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RemoteAccess\Parameters

This MUST be of type REG_DWORD. This SHOULD be a combination of the various flag values given in the following table.

Value	Description
0x00000001	This specifies that for Callback Control Protocol (CBCP) [RFC1570] in PPP, there needs to be a delay before the RRAS server performs the actual callback.

0x00000004	NetBEUI Framing is enabled.
0x00000008	RRAS server is enabled for IPv4 traffic to be tunneled.
0x00000010	RRAS server is enabled for IPX traffic to be tunneled.
0x00000020	RRAS server is enabled for AppleTalk protocol traffic to be tunneled.
0x00000040	Shiva Password Authentication Protocol (SPAP) can be negotiated for remote access and demand-dial connection authentication.
0x00000080	Packets between the WAN endpoints SHOULD be encrypted.
0x00000100	MSCHAP protocol can be negotiated for remote access and demand-dial connection authentication.
0x00000200	The use of LCP extensions as defined in [RFC1570] is allowed.

0x00000800	PPP peer needs to be authentication.
0x00001000	Packets between WAN endpoints SHOULD be encrypted using the strongest possible algorithm. The exact algorithm is RRAS implementation-dependent.
0x00002000	Bandwidth Allocation Control Protocol (BACP) [RFC2125] is allowed for remote access connections.
0x00004000	Remote access connections without authentication are allowed on the RRAS server.
0x00008000	EAP protocol can be negotiated for remote access and demand-dial connection authentication.
0x00010000	Password Authentication Protocol (PAP) [RFC1334] can be negotiated for remote access and demand-dial connection authentication.
0x00020000	MD5-CHAP [RFC1994] can be negotiated for remote access and demand-dial connection authentication.
0x00040000	IPsec needs to be negotiated for L2TP [MS-L2TPIE] tunnel type connections.

0x00100000	MOBIKE [RFC4555] extension support is not allowed for IKEv2 remote access connections.
0x00200000	Use of LAN Manager passwords [RFC2433] is allowed for remote access and demand-dial connection authentication.
0x00400000	Connections to the RRAS server using directly connected serial ports can be accepted without authentication.
0x00800000	MSCHAPv2 [MS-CHAP] can be negotiated for remote access and demand-dial connection authentication.
0x01000000	Callback functionality using CBCP [RFC1570] is enabled.
0x02000000	Machine authentication is allowed on the RRAS server.
0x04000000	Authentication using certificates is allowed on the RRAS server.
0x08000000	RRAS server is enabled for IPv6 traffic to be tunneled.
0x10000000	Preshared key can be used for authentication using L2TP over IPsec [MS-L2TPIE].
