If UPnP (automatic port configuration) method doesn't help, you can try forwarding the port manually. Port forwards are setup in your router. The default one is
1194 but you can forward any different port. A summary of the steps to setup a port forward in your router are:
- Login to your router.
- Navigate to your routers port forwarding section, also frequently called virtual server.
- Create the port forward entries in your router.
- Test that your ports are forwarded correctly.
Please make sure that you have also configured your node to run the services on that port as described here.
