8 .1PPTP Service Basic Configuration

PPTP Service Basic Configuration

Point-to-Point Tunneling Protocol (L2TP) is one of the ways to implement virtual private network (VPN). L2TP uses Transmission Control Protocol (TCP) to create control channels to send control commands, and uses Generic Routing Encapsulation (GRE) channels to encapsulate Point to Point Protocol (PPP) packets to send data.

Start Service

Select VPN service -PPTP service configuration, select enable and PPTP service, click save to start PPTP service.

Description of Configuration Items:

Local Address: The local address of the local PPTP (default is sufficient, be careful not to conflict with other LANs).

Start Address: The start and end addresses of the PPTP client (default, be careful not to conflict with other Lans).

DNS: The DNS address assigned to the PPTP client, which can be the local address of the PPTP service (default), or the address of other DNS servers.

Configure Account

Refer to local account management.

When creating an account, PPTP needs to be checked in the available authentication methods.

Working Mode Specification

In NAT mode, where the addresses of PPTP clients are converted into PPTP local addresses through NAT and then communicated with other IP address.

In routing mode, the PPTP client directly forwards access to other Intranet addresses without NAT.

Advanced Configuration - Authentication Mode

Click on Advanced Configurable to see the authentication mode selection. By default, local authentication is used, and third-party RADIUS authentication is optional.
