strange requests from Vanguard Securities: 53,137,138
In browsing vanguard.com I find it slow, also they cause unexpected
logging in my /var/log/messages file. To kill these I updated itpables
to open said ports.
# /opt/sbin/ziptables.vanguard input
iptables -I INPUT -j ACCEPT -s 184.108.40.206/24 -p udp \
-m multiport --ports 53,137,138
Why are they examining these ports? No one else is.
