OpenVPN Port 1194 not accepted in iptables policy but still accessible

I am able to connect to my OpenVPN server via port 1194, even though this port is not allowed (accepted) in my iptables config. I can confirm no exception is defined as this command gives no output: iptables -S | grep 1194

I would expect not to be able to connect as my iptables config states a -P INPUT DROP policy at the beginning of the file.

It gets even better. Running nmap -sU -p 1194 localhost from the host machine gives:

PORT     STATE  SERVICE1194/udp closed openvpn

I would expect this port to be open, right? I ran this command at the moment of an open VPN connection.

Also, according to this article, I should see this line:

udp    0   0 192.168.70.3:1194   0.0.0.0:*  5713/openvpn-openssl

Unfortunately, I don't.

OpenVPN access server configuration (Admin UI)Only UDP port 1194 has been opened (port forwarded) on the control panel of my internet provider so it can't be the TCP 443 port.

So the final question is:How is it that I can connect without having to allow this port in my iptables configuration?
