[CentOS] firewalld trouble opening a port

Hey all,

 I'm having a little trouble opening up a port on a C7 machine.

 Here's the default zone:

[root at appd:~] #firewall-cmd --get-default-zone
home

So I try to add the port:

[root at appd:~] #firewall-cmd --zone=home --add-port=8181/tcp
success

Then I reload firewalld:

[root at appd:~] #firewall-cmd --reload
success

Simple! That should do it. Right? Well not quite.

Cuz when I telnet to that host on that port, it's not connecting:

#telnet appd.mydomain.com 8181
Trying xx.xx.xx.xx... <---obscuring the real IP
telnet: connect to address xx.xx.xx.xx: Connection refused
telnet: Unable to connect to remote host

Yet, that port is definitely listening on the host:

[root at appd:~] #lsof -i :8181
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
java    13423 root  333u  IPv6 3526508      0t0  TCP *:intermapper (LISTEN)


And if I stop the firewall momentarily :

I can telnet to that port from a remote location:

#telnet appd.mydomain.com 8181
Trying xx.xx.xx.xx...
Connected to appd.mydomain.com.
Escape character is '^]'.

Of course I bring up the firewall right away once I'm done testing:

[root at appd:~] #systemctl start firewalld
[root at appd:~] #systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled)

May 09 14:56:20 appd systemd[1]: Started firewalld - dynamic firewall
daemon.

Any ideas on what I'm doing wrong?

Thanks,
Tim
