| Id |
| The profile ID of the PPTP profile. |
| Keepalive |
| When set to on(1), PPTP echo requests as described in RFC 2637 are sent in regular intervals during the connection. If set to off(2), no PPTP echo requests will be performed, delete(3) determines the entry is marked for discard. Enumerations: |
| MaxRequests |
| The maximum number of outstanding PPTP echo replies, until the PPTP control connection is droped and all associated calls are terminated. Range: 0 to 100 |
| MaxBlockTime |
| Maximum time (in msec) the GRE Send Window is blocked. If the GRE Send Window is full, no packets can be forwarded and the Maximum Time is passed, the GRE Send Window is resetted to prevent unsolvable situations. Range: 0 to 10000 |
| MaxAckTimeout |
| Maximum value the adaptive Acknowledgment Timeout (in msec) can reach while it is calculated. According to RFC 2637. Range: 2000 to 5000 |
| ReassemblyTimeout |
| Maximum time (in msec) for rearranging out-of-sequence packets. After this time outstanding packets will be supposed missing. Range: 100 to 1000 |
| MaxSWin |
| Maximum GRE send window size Range: 0 to 256 |
| XmitWaitTime |
| Wait time (in msec) before transmitting data. Range: 0 to 32 |
| MaxCtlConn |
| Defines the maximum number of incoming PPTP control connections per remote IP address. Range: 1 to 1024 |
| GreWindowAdaption |
| Enables/disables the sliding GRE window algorithm. Enumerations: |
| Host |
| Specific name of the PAC or PNS being used for the PPTP Start Control Connection Request/Reply. Length: 0 to 255 |
| Vendor |
| Vendor specific string describing the type of PAC or PNS being used for the PPTP Start Control Connection Request/Reply. Length: 0 to 255 |
| FirmRev |
| This variable contains the firmware revision number of the issuing PAC or PNS. If not specified (set to 0) the global Firmware Revision will be propagated. Range: -1 to 999 |
