Hello.

Is that normal that firewall blocked SSDP and router so many times?

you should unblock that (svchost) using the wizard  @hdx1337

Eset's default firewall rule for SSDP is to only allow inbound port 1900 traffic from devices in the Trusted Zone. If you are using Eset's Known Network setting of Public -or- it is set to Use Windows Settings and the Windows Firewall active profile is Public, then nothing is set in Eset's Trusted Zone. Hence, the large number of blocked incoming SSDP connections shown.

It appears to me the firewall settings on the router are not properly configured and it is allowing incoming port 1900 traffic from connections that are not part of your internal network. The block count for router connections should be only 125 which is the sum of the inbound connections from the Samsung and Huawei devices.
