The firewall supports PPTP as described in RFC 2637. To allow users to access your network through PPTP, specify settings and click Apply. Then, click Add members and select users. To view users who are allowed access using PPTP, click Show members.

Dec 07, 2005 · Today I was setting up a VPN server and had to figure out what ports and protocols to enable on our Cisco PIX 515E firewall. Here they are: PPTP: To allow PPTP tunnel maintenance traffic, open TCP 1723. To allow PPTP tunneled data to pass through router, open Protocol ID 47. L2TP over IPSec To allow Internet Key Exchange (IKE), open UDP 500. PPTP uses two protocols: GRE to encapsulate PPP packets; and a control channel at TCP port 1723. Any stateful firewall would have a problem with allowing PPTP protocol without any special “fixup” because of the two protocols needed for communication (GRE and TCP 1723). On the corporate router and firewall, the TCP/IP port on which PPTP creates a socket (1723) must be open to both inbound and outbound traffic. If the rest of the network is protected by a firewall that disallows inbound and outbound Internet traffic, then a single point of entry to the LAN is established, which is protected by the user-based GRE connection for PPTP is recognized as related and passed. Attaching the firewall to an interface. If you run PPTP on the same router you are configuring the firewall, you need to attach it to interfaces you want PPTP connection on as "local". If you have a firewall in front of your PPTP server, attach it as "in". Full example Nov 08, 2000 · The most common approach is to place the VPN server behind the firewall, either on the corporate LAN or as part of the network’s “demilitarized zone” (DMZ) of servers connected to the Internet.

Enable ‘PPTP-In’ for the Inbound rule, and ‘PPTP-Out’ for Outbound Rule. After you have completed all these steps, you can now enjoy safe, secure, and anonymous browsing through your VPN, without the need to abandon Windows Firewall.

2. Add firewall rules for the PPTP traffic to the local firewall policy. set firewall name WAN_LOCAL rule 30 action accept set firewall name WAN_LOCAL rule 30 description PPTP set firewall name WAN_LOCAL rule 30 destination port 1723 set firewall name WAN_LOCAL rule 30 protocol tcp With this You will be able to set the binding interface in firewall rules if needed and apply specific policies on the interface/user [ admin@MikroTik] > interface pptp-server add name=pptp-user1 user=user1 Now Your MikroTik Router is ready to serve PPTP VPN Connections! If you want to learn How to set-up L2TP VPN Server. If you did all right, you now have a working PPTP VPN server. Important: Don’t forget to open port 1723 (tcp) in your firewall settings: /ip firewall filter add chain=input comment="PPTP VPN" dst-port=1723 protocol=tcp. If you need any help or I did something wrong, leave a comment and I will try to do my best to help you.

The firewall supports PPTP as described in RFC 2637. IPsec policies. Internet Protocol Security (IPsec) profiles specify a set of encryption and authentication settings for an Internet Key Exchange (IKE). You can use profiles when setting up IPsec or L2TP connections.

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.
