Hi!
It's hardcoded into KMRCL to listen on 0.0.0.0. ==> It's possible to reach your lisp server directly from outside your server.
Don't forget to close your ports!
If you're using Linux, outside interface is eth0 and *apache-port* is 3000 (default), then use the following line:
iptables -A INPUT -i eth0 -p tcp --dport 3000 -j REJECT
