Block Port 49276 -- Is this a problem?

Hi All,

First time I have seen this request to allow or block my base router address

192.168.254.254
UDP
Port 49276

I have blocked it but did not have Comodo remember the blocking in case I need to allow it next start. I have had CIS installed for probably a month and never seen this request before.

Should I remember the block or allow it in future?

Thanks

What are the Source and Destination port of the alert? Source would be UDP 49276 but the destination port is not known.
