6. Select Unable to accept incoming TCP Connections.
7. Click the In/Out UDP Packets
8. Select Unable to send or receive UDP datagrams on any port.
9. Close WinMX and continue to Step 5

OR

Option 2

If you have administrator access for your computer/network and you are comfortable with making changes to your router configuration then define specific ports for WinMX to use:

a. All versions of WinMX

1. Open WinMX
2. Click the Settings button
3. Click the plus sign in front of Internet Connection.
4. You should now see a new list drop down under Internet Connection.

Step 4

Portforward the router for WinMX. Choose your router make and model from the list on the following page: Port-forwarding Tutorial **Note: Do not select the ad for PFConfig unless you wish to pay for a third-party program to do it automatically for you. You can do this process yourself for free.**

For all routers:

Fill in the boxes on the page like so:

1. WinMX’s port for incoming TCP connections: 6699
2. WinMX’s port for incoming UDP connections: 6257
3. Enter the IP you want to forward to: Use the IP address you set for your computer in Step 3.
4. The rest of the blanks on the page will fill in automatically, showing you exactly how to set up portforwarding for WinMX in your router. Follow the instructions you are given.

When you have finished the portforwarding process, open WinMX and test your uploads. If you still are unable to upload continue to Step 5.

h. Other Firewall Programs

1. Go to your firewall’s settings option.

4. Save your changes and restart your firewall program.

Restart WinMX and try uploading to others again. If you are still unable to upload continue to Step 6.

Step 6

If you have a network with more than one computer running WinMX repeat Steps 1 though 5 on the other computers and assign different ports for them to use.

For example:

Computer 1 TCP 6699 UDP 6257

Computer 2 TCP 16699 UDP 16257

Computer 3 TCP 26699 UDP 26257

Computer 4 TCP 36699 UDP 36257

Continue to Step 7

Step 7

If you are still unable to upload at this point you might be one of the unlucky few who have Internet Service Providers who block ports or filter out peer-to-peer traffic. If this is your case, some people have had good results by trying alternate ports or setting TCP and UDP ports to "Unable" (as shown in Step 1 for education and company networks).
