I had this connection with Hyperwrt too!
Always denied and Service "bootpc" it was mentioned ...

ping and tracert to the ip is not possible, it times out ...

IP is a private one, so ripe unuseful ...

Is this another router?

Following to port it is:

68/tcp bootpc Bootstrap Protocol Client
68/udp bootpc Bootstrap Protocol Client

Connected is only one pc and sometimes my notebook ... (pc mostly
turned off then)
