PPTP connections may be limited or impossible to setup though a masqueraded/NAT IP connection. 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 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). Full authentication and accounting of each connection may be done through a RADIUS client or locally. PPTP includes PPP authentication and accounting for each PPTP connection. 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. This way it is possible to setup bridging without EoIP. 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 the sending of raw Ethernet frames over PPP 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). PPTP incorporates PPP and MPPE (Microsoft Point to Point Encryption) to make encrypted links. PPTP encapsulates PPP in virtual lines that run over IP. PPTP is a secure tunnel for transporting IP traffic using PPP.
