Do you have to do something in the router to make it forward the incoming packets to your pc? Normally you shouldn't have to. What happens if you configure the network manually (system-config-network) and turn off NM? You can try to look at the packets with wireshark and see if you can figure out what it's waiting for. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
