I set rules for Out/In but Zentyal simple bypassing it.
I saved changes, restart services but Traffic shaping is not working for 100% (priority 7 for IP (with p2p) and prior 0 for other IP. P2P keeps taking whole bandwidth).
I attached pic with my settings.
IP 192.168.5.77 should have lowest priority, during tests it turned out that machines with priority 0-2 has only 10-20% of bandwidth available while 77 with lowest priority got almost all bandwidth .
