Problem with firewall?

Does anyone know for what is this port 26526 ?

My firewall detect 5660 attacks at the moment and most are from “Windows Operation System” and this port 26526.

Log is attached

Seems like just a random port number to me… My guess it was scan \ attack \ exploit attempt that got blocked.

Connection attempts were from multiple IPs and with a few seconds gap between them, so maybe it was DDoS attempt or something.

Are you using a Torrent or other p2p client that uses port 26526?

When closing down a peer to peer program it will take several hours before all the other computers on the network will know your computer is no longer available. During that time you will see requests getting blocked.
