First Check your windows firewall setting and check out and make sure you are allowing the ports of the program you need ports open.
most isp's only block certain ports for quratine or bandwidth hogging programs. Blocking Ports is a natural defence against hackers and other potential threats, because they restrict the connection comming into your computer. modems generally don't have such security, therefore it's important that you know the difference between the modem and the router.
Routers are meant to...route the given connection to other computers, The modem is used to dial in or connect to the ISP for the connection and the initial IP. Most linksys routers have the default 192.168.1.1 as it's setupIP and username nothing and password admin. As for other routers you can find it at the product page or support sites. Also, portforward.com has software and guides to help you find your router.
If you are 100% sure you do not have a router, it means that your ISP has one that shares the internet , you can find the router but you can't log in because you don't know the router user name and password...

How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
