I have strange situation. My cameras stop working over android app connected over p2p to nvr4108e-hs. I can see in pfsense that all connection are blocked by Default deny rule IPv4 (1000000103). Its funny becouse 3 year work like a clam in same settings and same software. I can access cameras when iam on the same network or use VPN outside of cameras lan. But i think p2p sould work without opening some extra port on firewall.
I see a lot of blocked port in FW log ...:21727,25266, 41836, 63583, 32855, 48152, 28639, 32684, 2128,.....and so on. All this ports are UDP. So can someone have idea what to check ?
