VPN Account

PPTP and L2TP server share the same account database set in VPN Account page.

Name:

A user-defined name for the connection.

Tunnel:

Select Enable

to activate the account. PPTP2TP) server is waiting for the client to connect to

this account.

Username

: Please input the username for this account.

Password

: Please input the password for this account.

Connection Type

: Select Remote Access for single user, Select LAN to LAN for remote gateway.

Peer Network IP

: Please input the subnet IP for remote network.

Peer Netmask

: Please input the Netmask for remote network.

PPTP

The Point-to-Point Tunneling Protocol (PPTP) is a Layer2 tunneling protocol for implementing virtual

private networks through IP network. PPTP uses an enhanced GRE (Generic Routing Encapsulation)

mechanism to provide a flow- and congestion-controlled encapsulated datagram service for carrying

PPP packets.

In the Microsoft implementation, the tunneled PPP traffic can be authenticated with PAP, CHAP,

Microsoft CHAP V1/V2 or EAP-TLS. The PPP payload is encrypted using Microsoft Point-to-Point

Encryption (MPPE) when using MSCHAPv1/v2 or EAP-TLS.

Note: 4 sessions for Client and 4 sessions for Server respectively.

PPTP Server

In PPTP session, users can set the basaic parameters(authentication, encyption, peer address, etc)

for PPTP Server, and accounts in the next page of PPTP Account. They both constitutes the PPTP

Server setting.

PPTP Funtion

: Select Enable to activate PPTP Server. Disable to deactivate PPTP Server function.

WAN Interface

: Select the exact WAN interface configured for the tunnel. Select Default to use the

now-working WAN interface for the tunnel.

Auth. Type:

The authentication type, Pap or Chap, PaP, Chap and MS-CHAPv2. When using PAP,

the password is sent unencrypted, whilst CHAP encrypts the password before sending, and also

allows for challenges at different periods to ensure that an intruder has not replaced the client. When

passed the authentication with MS-CHAPv2, the MPPE encryption is supported.

Encryption Key Length

: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits.

Default is Auto, it is negotiated when establishing a connection. 128 bit keys provide stronger

encryption than 40 bit keys.

Peer Encryption Mode

: You may select “Only Stateless” or “Allow Stateless and Stateful” mode. The

key will be changed every packet when you select Stateless mode.

IP Addresses Assigned to Peer: 192.168.1.x: please input the IP assigned range from 1~ 254.

Idle Timeout

: Specify the time for remote peer to be disconnected without any activities, from 0~120

minutes.

Click Apply to submit your PPTP Server basic settings.

PPTP Client

PPTP client can help you dial-in the PPTP server to establish PPTP tunnel over Internet.

Name

: user-defined name for identification.

WAN Interface

: Select the exact WAN interface configured for the tunnel. Select Default to use the

now-working WAN interface for the tunnel.

Username

: Enter the username provided by your VPN Server.

Password

: Enter the password provided by your VPN Server.

Auth. Type

: Default is Auto if you want the router to determine the authentication type to use, or else

manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP (Password

Authentication Protocol) if you know which type the server is using (when acting as a client), or else

the authentication type you want clients connecting to you to use (when acting as a server). When

using PAP, the password is sent unencrypted, whilst CHAP encrypts the password before sending,

and also allows for challenges at different periods to ensure that an intruder has not replaced the

client.

PPTP Server Address

: Enter the IP address of the PPTP server.

Connection Type

: Select Remote Access for single user, Select LAN to LAN for remote gateway.

Time to Connect

: Select Always to keep the connection always on, or Manual to connect manually

any time.

Peer Network IP:

Please input the subnet IP for Server peer.

Peer Netmask:

Please input the Netmask for server peer. Click Add button to save your changes.

Example: PPTP Remote Access with Windows7

(Note: inside test with 172.16.1.208, just an example for illustration)

Server Side:

Configuration > VPN > PPTP and Enable the PPTP function, Click Apply.
