Need to set port forwarding for filemaker to network

Port forwarding is a process that you set up on your router and is independent from your OS.
Go here, and select the router you are using. On the next page (after skipping that annoying ad) you will see a list for different software setup's. Depending on you router, you might find Filemaker in the list.
(I checked Linksys WRT54G, and found it.)
Filemaker Server and FileMaker Pro with TCP/IP are using port number 5003with both the UDP and TCP protocols when communicating via TCP/IP.
UDP is only used for the initial contact, all other TCP/IP communication is using TCP.

There is a good video description, which I highly recommend if you're new to this. You can find that here.

If you have more questions, come back here or head over to, which has an excellent forum and the guys know what they are talking about.

Good luck!

Xbox360 elite

do u have a router and if so u need to make sure these ports are open

If you have not already forwarded ports for your xbox through your router then that may be your problem.

The following ports must be available to your Xbox 360 console for Xbox LIVE to operate correctly:
  • TCP 80
  • UDP 88
  • UDP 3074
  • TCP 3074
  • UDP 53
  • TCP 53

World of Warcraft

Sounds like you need to do some port forwarding.

World of Warcraft communicates on port 3724 with the TCP protocol. The patching process requires port 3724, 6112, and 6881-6999. Once again to download the patches for World of Warcraft you should forward the following ports.

3724 TCP6112 TCP6881-6999 TCP

If you can not forward ranges of ports and are only planning on having one computer playing WoW, just forward ports 3724 TCP and 6112 TCP. The 6881-6999 port range is mainly used where multiple computers on a network may be trying to play WoW at the same time.

Ventrilo: From their web site: Click on the "Port number" input box and enter the servers port number. The program will automatically display the default port number of 3784 but you can change this to what ever the server needs it to be.

So forward 3784 or the port number you chose. for a walk through on how to do the forwarding.

Hope that helps!

Bridge RCA Thomson DCM315R


Usually cable providers provide public ip directly to your company ( already bridged ). so no need to configure your modem to bridge.
- Connect the computer directly to the modem and if possible, let me know the ip address of your PC, So we can find the modem already bridged.
- If its already bridged, then Open the ports on your Router ( port number : 3389 for TCP ) or else you may try DMZ Host on your router to check whether it works.

DMZ ( Demilitarize Zone ) host which opens all ports on your network and shows ur computer to the outside Network which is not really secured one. but you can try it for testing purpose whether it let you to use remote desktop.

Hope this will help you

Port Forwarding

Instructions for DG834, DG834G, DG824M, FR114W, FM114P, FR114P, FR328S, FVL328, FVS328, FVS338, FVX538, FWAG114, FWG114P, or FVS318v3 These routers do port forwarding by assigning port numbers to a "service" associated with the application you want to run. "Rules" are set for particular services. Rules block or allow access, based on various conditions such as the time of day and the name of the service. To Create a New Inbound or Outbound Rule 1. Submit the router's address in an Internet browser. (The default is 2. Enter the router's username and password. 3. From the main menu, click Security > Rules. 4. Click Add for inbound or outbound traffic, as appropriate to the application you are planning to run. 5. Select the Service. The services the router knows about are listed in the drop down. If the service you want is not listed, add it as described in the next section. 6. Select the Action, for example ALLOW always. 7. For Send to LAN Server, enter the IP address of the local server. Note that this is also the IP address the computers on your LAN will access. 8. For WAN User choose Any, or limit access to particular IP addresses. 9. For Log selection it is reasonable to turn logs on, especially at the beginning when you are unsure of the result of the changes you are making. Later, you may want to set logs to "Never" for performance reasons. 10. Click Apply. As noted in user manual for some models: * Consider using the Dynamic DNS feature on the Advanced menu, so that external users can find your network when the DHCP lease is renewed by your ISP. * If your own LAN server uses DHCP, and your IPs change on rebooting, consider using the Reserved IP Address feature in the LAN IP menu. To Add a Service for These Routers 1. Click Security > Services > Add Custom Service. 2. Enter any name you choose for the service. 3. Select whether the service is to use TCP or UDP. If you are unsure, select both. 4. Enter the lowest port number used by the service. 5. Enter the highest port number used. If the service uses only one port number, enter the same number. 6. Click Apply.
