PLex brodcast on public ip

#1

Hello,
After an audit on my firewall, I detect that there is a lot of boradcast from other online server who’s running PLex (UDP 32414 and 32412).
I suppose it come from the seedbox installation that online propose on their website, so why online didn’t add rule to block this traffic?
Can we open a ticket with the offending ips and ask to take action ?

Regards
