i dont use bgp .
i have a ip range from a provider. could it be his device what bgp has open, to communicate with his network?
Do you have FRR installed? I think the FRR package on OPNSense is able to auto open firewall ports. If you don't use a dynamic routing protocol like BGP, IS-IS, RIP or OSPF you should be better of removing FRR from the firewall. If you do use for example OSPF then you can uncheck: Routing -> General -> Firewall Rules. Don't forget you then need to manually adjust appropiate firewall rules.
