Connection Issues

Try going to http://www.canyouseeme.org and verifying that your port is indeed open, and giving the correct IP address to your players.

 

OK, now that we established that the port is being blocked let's see if we can find out what is blocking it.

For the first test, I would go into your router's settings and create a DMZ pointing to your internal IP address for the computer hosting the d20Pro game (the one that starts with 192.168.X.X). The DMZ setting allows all traffic to be sent to the internal IP address you specify. If this solves the issue we can isolate the cause as some setting(s) in your router causing the blocked port, or it could be mis-routing. Please see the manufacturer's website on how to add port forwarding, or follow the basic instructions here

If DMZ does not fix the issue, the blocked port is caused by some software you have loaded on your computer. You can take your internal IP out of the DMZ and turn DMZ off.

Next I would check Windows Firewall (even if you have this feature off).

Open Windows Firewall by clicking the Start button , clicking Control Panel, clicking Security, and then clicking Windows Firewall.


Click on "Change Settings" then allow or enter in administrator password.


Click "Allow Another Program."


Pick d20Pro from the list, then click on "add"


Select d20Pro from the list and make sure both spaces for check marks have check marks.


Press "OK" at the bottom.



Next, I would check Norton Internet Security...
Go to (in NIS2011) Settings > Internet Settings > Smart Firewall > Advanced Settings > General Rules > Add.
Select ADD and next.
Select "to and from" and next.
Select "any computer" and next.
Select "TCP and UDP" and "Only the ports and ....." and "Add".
Select "Individual ports", select "Local" and type in 10101" and click OK.
Click Next, Next, type in a rule name and click Next.
Click "Finish"


If this does not solve your issue, let us know.

Good Luck!
