At first I though the whole problem was with querying the server for a list of open files and not actually connecting to the files, so I made a local database opener file that net protector 2015 crack runs a startup script that opens all the files I need.
Many web applications use UDP,.g.
UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in ietf RFC 768).
By default, the firewall in Windows XP Professional SP 2 is turned on and must be configured to open the ports shown above.TCP guarantees delivery of data packets on port 5003 in the same order in which they were sent.But in the end I know for sure that port 5003 of our external IP is being forwarded to our FMP Server while UDP is not being forwarded.Only when a connection is set up user's data can be sent bi-directionally over the connection.UDP port 5003 would not have guaranteed communication as TCP.When using FileMaker Server in an environment that utilizes a firewall, be sure to configure the firewall to allow the specific ports used by FileMaker Server as shown above.When the FileMaker Server Admin application is launched when the firewall is on, a Windows Security Alert will be displayed with the name of the program set to Microsoft Management Console.TCP vs UDP - TCP: reliable, ordered, heavyweight, streaming; UDP - unreliable, not ordered, lightweight, datagrams.TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications.
For sake of simplicity, you can consider that I am trying to connect from outside the LAN.
UDP on port 5003 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level.
This is weird as the communication is fine once a file is open.I don't understand why I would have to "On the router set up a stack filter on port 5003 so udp is not passed in either direction." but I did set a packet filter to do just that.But it turns out that I can only open 1 file (even through a script) every 5 minutes, the second Open script steps returns a "File cannot be found".Restart your computer after configuring the firewall.UDP on port 5003 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice.This port is not configurable.I try to open another file from the same location and the host list is blank.
