sharing WordPress in WAMP through internet (insecure?)

I’ve managed to put my WAMP server online and then port fowarded to the internet configuring the router. However I don’t know if it’s secure. What do you say?

It already worked locally.
Then I’ve changed this on httpd.conf,

<Directory “d:/wamp/www”>
AllowOverride All

# onlineoffline tag – don’t remove
# Order Deny,Allow
# Deny from all
# Allow from 127.0.0.1
# Allow from ::1
# Allow from localhost
# Allow from 192.168.1.60
Order Allow,Deny
Allow from all
</Directory>

and,

<Directory />
AllowOverride none
Order Deny,Allow
Deny from all
</Directory>

I’m listening on port 80.

Then I went to my router configuration, to Virtual Servers (in TP-Link), and make everything on port 1234 go to port 80 on my local static ip address.
So, http://<my-public-address&gt;:1234 goes to my server.

Finally, I’ve changed the Site URL in WordPress to “http://<my-public-address&gt;:1234”

Everything works, but I don’t know if it has strong vulnerabilities. That thing about tunneling a public port to my port 80.
