Enable your firewall and pass the below entries

First thing for which users you want to block this port means all users or
users from Outside(LAN users are allowed) only


For first case
iptables -A  INPUT -p tcp  --dport 3127  -j REJECT


For second case

iptables -A  INPUT -p tcp  -s ! LANRange--dport 3127  -j REJECT

iptables -A  INPUT -p tcp -s ! 192.168.1.0/255.255.255.0 --dport 3127  -j
REJECT
