P2P drop from connection

Good day.

Sorry for my spelling.

My setup I have is 1Gbps fibre to my home. It is connected to a Rb4011 router configured to run my PPP. The income of the Wan is in port 1, from there I am sending it via Sfp+ to my CSS326 switch. I have like 5 connections on the switch. All 5 connections is also connected via its own PPP connection i created for login. My Hap Ac3 is connected to the CSS326 via port 10 on my css326. All my connections are well, pings is 7ms to google.com.

Here comes my problem.

As soon as i start a P2P connection ( Multiplayer games, CCTV, NVR, CMS Ect) every thing from the CSS326 Does not connect to the internet all pings 8.8.8.8 Fails with time out.

On the main link Rb4011 I can still do the ping and it is still good standing. any one that can give me some advice.

Good evening all. this is just an update.
The problem was my ISP that blocs P2P connections.
