Hi There,
my Provider Unitymedia send me a letter.
Open Port 53udp? is open.
I´ve checked this witrh nmap from an external Network.
The result:
PORT STATE SERVICE
53/tcp filtered domain
81/tcp open hosts2-ns
135/tcp filtered msrpc
139/tcp filtered netbios-ssn
179/tcp filtered bgp
222/tcp open rsh-spx
444/tcp open snpp
445/tcp filtered microsoft-ds
3551/tcp open apcupsd
I have no firewall rules in my IP Fire… but why is Port 53 open?
Is there a chance to wright in german? My English is very bad
