Possible values:
• PAP/CHAP/MS-CHAP (default value): Primarily run CHAP, on
denial, the authentication protocol required by the PPTP part-
ner. (MSCHAP version 1 or 2 possible.)
• PAP: Only run PAP (PPP Password Authentication Protocol);
the password is transferred unencrypted.

ation Protocol as per RFC 1994); the password is transferred
encrypted.

Encryption Only for PPP Authentication = MS-CHAPv2
If necessary, select the type of encryption that should be used
for data traffic to the connection partner. This is only possible if
STAC or MS-STAC compression is not activated for the con-
nection. If Encryption is set, the remote terminal must also sup-
port it, otherwise a connection cannot be set up.
Possible values:
• None (default value): MPP encryption is not used.
• Enabled. MPP encryption V2 with 128 bit is used to RFC
3078.
• Windows compatible: MPP encryption V2 with 128 bit is
used as compatible with Microsoft and Cisco.
LCP Alive Check Check whether the availability of the remote terminal is to be
checked by sending LCP echo requests or replies. This is re-
commended for leased lines, PPTP and L2TP connections.
