# Understand TMS IP Ports
### TMS Server IP Addresses
* The primary TMS server is hosted at '[www.wizarview.com](http://www.wizarview.com)'. This domain resolves to the main server's IP address, which is the central point of communication for TMS operations.
* To ensure global accessibility and redundancy, TMS also utilizes several assistant servers located in various countries. Each of these servers has a unique IP address to facilitate localized operations.
#### Main Server:
* [www.wizarview.com](http://www.wizarview.com) \[default 129.153.119.200[
](https://www.ip2location.com/demo/129.153.119.200)]\(port 80, 443)
#### Communication Server:
* mqtt.wizarview\.com \[ 129.153.221.231[](https://www.ip2location.com/demo/129.153.221.231)]\(port 11884, 11885)
#### Download Servers:
1. [www.wizarview.com](http://www.wizarview.com) \[129.153.119.200 [](https://www.ip2location.com/demo/129.153.119.200)] (port 443)
2. dlus.wizarview\.com\[141.148.131.11[](https://www.ip2location.com/demo/141.148.131.11)] (port 443 8680）
3. dluae.wizarview\.com \[193.123.67.48[](https://www.ip2location.com/demo/193.123.67.48)] (port 443 8680)
4. dlsg.wizarview\.com \[129.150.38.203[](https://www.ip2location.com/demo/129.150.38.203)] (port 443 8680)
#### Monitor server:
* remoteme.wizarview\.com\[193.123.67.48[](https://www.ip2location.com/demo/193.123.67.48)]\(port 12010, 12011, 12012)
* remotesg.wizarview\.com\[129.150.38.203[](https://www.ip2location.com/demo/129.150.38.203)]\(port 12010, 12011, 12012)
* dlus.wizarview\.com\[141.148.131.11[](https://www.ip2location.com/demo/141.148.131.11)] (port 12010, 12011, 12012）
### Ports Configuration
* TMS requires specific network ports to be open for seamless communication and operational efficiency. The exact ports used depend on the services and protocols TMS utilizes.
| Port | Server | Description |
| ----------------------- | -------------------- | ----------------------------------------------------- |
| TCP 80, 443 | Main Sever | User login and terminal HTTP request. |
| TCP 11884 | Communication Server | Used by terminal agent to keep connection. |
| TCP 8680, 8780, 8681 | Download Server | Used by terminal to download application. |
| TCP 12010, 12011, 12012 | Monitor Server | Used by terminal remote monitoring. |
| TCP 8080 | Main Sever | Used by terminal HTTP request. (Agent version < 4.4). |
| TCP 5222, 27777 | Main Server | Used by terminal access. (Agent version < 4.1). |
### Network Configuration and Security
* Ensure that the network configuration allows for the specified ports to be accessible. This might involve configuring firewalls and other security appliances.
* Prioritize security when configuring ports, especially those used for transmitting sensitive data. This is particularly crucial for smart POS systems handling financial transactions.
