Hello!
If your device have Public IP address (IPv4) or Global IPv6 than you can connect directly.
But if your device in local network under NAT you may confiture port forwarding to local IP address (see #24)

Thank you for your reply, one more question
If I don't have the router for configuration , so can it work ?

[vodvud]

By the network policy possible to connect to any device in local network if have one of below:

• Public IPv4
• Port forwarding to local IP
• Global IPv6

my local IP = 192.168.8.1
(If I use in local (Setup IP 192.168.8.201 in finger print), Port 4370 it woking well for local system)

But my system move to online now,

Example: I have hosting
PUBLIC IPV4 ADDRESS = 178.128.24.123
PUBLIC GATEWAY = 178.128.25.1
SUBNET MASK = 255.255.234.0
Port = 9876

So I try to connect directly from PUBLIC IPV4 to figure print(Setup public IP in finger print), but still not working. (see below picture). have any wrong from us ?, Kindly let me know

Hello.

• You should set your custom port number $zk = new ZKLib('178.128.24.123', 9876);
• Check if allowed UDP connection to your public IP
• Check connection quality between your application and fingerprint machine.

I tested it ok on xamp Windows, but on the linux apache2 server it's the same PHP code file but it doesn't work (only get data User, can not get attendance). Can you explain or give any special configuration instructions on apache2? Tks
