It sounds like you exchanged the router. By default, the local computers are not directly exposed to the Internet: the box that connects to the Internet filters incoming requests. Also, the router cannot know by itself which computer inside the local network is the "target" computer for new incoming connections -- all of them share one public IP address. Most routers allow outgoing traffic just fine, and keep track of where to forward replies to, but a Tor relay needs to receive "new" incoming connections. For this, you need to configure your router to do "port forwarding": one port, the port you configured your Tor relay to listen on, needs to be forwarded to the local IP address. You would usually do this via the admin web interface. All of them are a bit different, you need to look for a guide for your model. http://portforward.com/english/routers/port_forwarding/routerindex.htm has a lot of them listed.
Hope this helps!
