I've reset the R7000 back to factory defaults and forwarded UDP ports 500, 1701 & 4500 and TCP port 1723 to the internal Mac VPN server. If I try to connect to VPN from within the office internal network, it connects up just fine, leading me to believe the Mac OS Server is doing what it is supposed to do.
Mar 30, 2016 · TCP port 1701 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection. Attention! L2TP uses UDP port 1701. When the process is complete, L2TP packets between the endpoints are encapsulated by IPsec. Since the L2TP packet itself is wrapped and hidden within the IPsec packet, the original source and destination IP address is encrypted within the packet. Side note: TCP port 1701 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 1701 in the same order in which they were sent. Side note: UDP port 1701 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 1701 makes possible the transmission of a datagram message from one computer to an application running in another computer. L2TP (Layer Two Tunneling Protocol) – This protocol uses port 1701 TCP, Port 500 UDP, and port 4500 UDP. IPSec (Internet Protocol Security) – This protocol uses port 500 UDP and ports 4500 UDP. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. on a standar actiontec fios router. setting up VPN on a mac server, and port 1701 just wont open. I can open all other ports just fine, except for UDP1701 and 500 any guidance would be great!

This means if the LDAP traffic for port 389 is sniffed it can create security problems and expose information like username, password, hash, certificates, and other critical information. The port of LDAP TCP and UDP 389 is assigned by the IANA which is an international standardization institution. Opening a Port on Asus Routers. Most Asus routers are easy to configure and the port forwarding sections are no different. Some of the router models do use the term "server" instead of port forward which can be a little confusing. Overall the Asus routers have a high amount of customization within the user interface.
