Hello, I have the following scenario to test predefined hosts. (2 PCs with Win7) One PC with IP 192.168.1.10/24 and one other PC with 192.168.2.10/24 . The PCs are connected to a router who is in both subnets. Ping between PCs works and firewalls are disabled on both PCs. So Routing works. On PC with IP 192.168.1.10 I only have enabled the predefined host with 192.168.2.10:12345 and on the other PC there is only predefined host with 192.168.1.10:12345 Both Sync clients are configured with ports 12345. With Netstat I see that Bittorrent Sync is listening on these ports. In debug-log I can see an entry with ping directly and the IP and port of the other PC. In my router I can see that are UDP packets are runnung through the router to the right IP and port. Also with wireshark I can see some Packe But no synchronisation... Where can be the mistake? Or is the predefined host function not ready to use? Regards John
