RouterOS v3 Configuration and User Guide
Quick Setup Guide
To make a PPTP tunnel between 2 RouterOS routers with IP addresses 10.5.8.104 (PPTP server) and
10.1.0.172 (PPTP client), follow the next steps.
Configuration on PPTP server router:
Add a user:
[admin@PPTP-Server] ppp secret> add name=jack password=pass \
\... local-address=10.0.0.1 remote-address=10.0.0.2
Enable the PPTP server:
[admin@PPTP-Server] interface pptp-server server> set enabled=yes
Configuration on PPTP client router:
Add the PPTP client:
[admin@PPTP-Client] interface pptp-client> add user=jack password=pass \
\... connect-to=10.5.8.104 disabled=no

Description
PPTP is a secure tunnel for transporting IP traffic using PPP. PPTP encapsulates PPP in virtual lines that
run over IP. PPTP incorporates PPP and MPPE (Microsoft Point to Point Encryption) to make encrypted
links. The purpose of this protocol is to make well-managed secure connections between routers as well
as between routers and PPTP clients (clients are available for and/or included in almost all OSs including
Windows).
Multilink PPP (MP) is supported in order to provide MRRU (the ability to transmit full-sized 1500 and
larger packets) and bridging over PPP links (using Bridge Control Protocol (BCP) that allows to send raw
Ethernet frames over PPP links). This way it is possible to setup bridging without EoIP. The bridge should
either have an administratively set MAC address or an Ethernet-like interface in it, as PPP links do not
have MAC addresses.
PPTP includes PPP authentication and accounting for each PPTP connection. Full authentication and
accounting of each connection may be done through a RADIUS client or locally.
MPPE 40bit RC4 and MPPE 128bit RC4 encryption are supported.
PPTP traffic uses TCP port 1723 and IP protocol GRE (Generic Routing Encapsulation, IP protocol ID
47), as assigned by the Internet Assigned Numbers Authority (IANA). PPTP can be used with most
firewalls and routers by enabling traffic destined for TCP port 1723 and protocol 47 traffic to be routed
through the firewall or router.
PPTP connections may be limited or impossible to setup though a masqueraded/NAT IP connection.
