Official NATKVM Port Range & SSH Mapping Tool

Internal IPv4 NAT Port Calculator

Select your server location to view its exact public IP, enter your assigned internal IPv4 address, and generate your 20 usable UDP/TCP ports and SSH terminal connection string.

1. Select Server Location (Shows Exact Public Node IP): 15 Global Nodes

2. Server Subnet Preset:

3. Enter Your Internal Private IPv4 (Host Range: .10 to .254): Type your internal IP (e.g., 192.168.122.10, 192.168.1.11) or simply the host number 10 - 254.

How NATKVM IPv4 Port Mapping Works

Each NAT VPS is assigned an internal private IPv4 address on either 192.168.122.0/24 or 192.168.1.0/24 starting from .10 up to .254.

Host .10: SSH Port is 1021, and allowed 20 ports are 1001 – 1020.
Host .11: SSH Port is 1121, and allowed 20 ports are 1101 – 1120.
Host .25: SSH Port is 2521, and allowed 20 ports are 2501 – 2520.
Protocol: All 20 ports forward both UDP and TCP seamlessly.
Dedicated IPv6: Remember every VM also has 1 Dedicated IPv6 on all default ports (22, 80, 443) without any NAT.
