Hi,
I am using RB750Gr3 as a home router. Router is connected to ISP Cable Modem with ether1 port. Modem is in bridge mode. I can access modem with 192.168.100.1 address. When I look drop invalid rules on input chain, I have seen too many logs like below.
Why cable modem sends request to public ip? Should I add filter rule to accept this packets.
