Howto:Which ports are used for PPTP connections ...
Nov 22, 2021 PPTP uses GRE (General Routing Encapsulation), TCP port 1723, and IP port 47. PPTP supports encryption keys up to 128-bits, and it uses MPPE ( Through the PPP connection, all of the protocols allowed by RAS can be transported: TCP/IP, NetBEUI, and IPX/SPX. To the RAS users it appears as though they're
Answer (1 of 3): PPTP was built on top of TCP in part, so this isn't entirely a valid list of options. The real answer is it depends on the needs of the game. An online chess game TCP … I commented out the lines for port 1723 and port 1821 (the one I wanted to use) and created two new lines with pptp 1821/tcp and pptp 1821/udp, … 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 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. Dec 31, 2020 However, PPTP is an obsolete and insecure protocol and you are better off switching to something like OpenVPN, which uses either UDP or TCP
PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality. The intended use of this protocol is to provide security levels and remote access levels comparable with typical VPN products. 2. PPTP. Think about the security standards of the web back in 1995.
