Port Redirection option
Introduction
Port Redirection is a IXC ACS functionality that allows you to create rules for remote access to devices connected to the local network, such as security cameras, DVRs, servers and IoT equipment. With this option, requests made from the internet can be correctly directed to a specific device within the client's network.

Port redirecting concept
Port redirection, also known as port forwarding, is a technique that allows external connections to reach an internal network device, even when it does not have its own public IP. This functionality is used when it is necessary to access a service from within the local network from the internet.
- What? Remote access to cameras and DVRs
- Hosting servers and applications
- What? Home automation systems
- What? Remote device management IoT
Configuration process
To configure a port redirecting rule in the IXC ACS, follow the steps below:
Access option Redirection on desired equipment
Click Add new rule
Fill in the requested fields:
- Service: Name to identify the rule (example: Camera Sala )
-Internal IP: IP address of the device within the local network
Protocol: Select TCP, UDP or TCP/UDP according to the service used
Internal door: Door used by service on device
External door: Port that will be accessed externally
- Click Save to apply the configuration
It is recommended that the internal IP of the device be fixed or reserved in DHCP, preventing the rule from working if the IP address is changed.
Protocols available
TCP: Protocol that prioritizes reliability and complete data delivery. Suitable for web browsing, access to file management and transfer interfaces.
UDP: Protocol that prioritizes speed and communication in real time. Suitable for online games, streaming and voice calls.
TCP/UDP: Enable both protocols simultaneously. Recommended when the service uses different types of traffic or when there is no certainty about the required protocol.
Practical example
- Remote access setting to an IP camera:**
- Service: Camera Room -Internal IP: 192.168.1.100
- **Protocol:**TCP
- Internal door: 8080
- External door: 8080 In this scenario, any external access to the port 8080 of the public IP will be redirected to the port 8080 of the device with IP 192.168.1.100 within the local network.
- A single device can use different ports and protocols simultaneously, such as:*
- Web server: TCP (ports 80 or 443)
- What? Games or streaming: usually UDP
Security considerations
When using door redirection, it is important to adopt good safety practices:
- Use Non-standard external doors whenever possible
- Keep devices up to date
- Configure strong pictures** in exposed services
- Evaluate use of VPN for safer remote accesses Troubleshooting If redirecting does not work properly, check:
- If the internal IP is correct and the device is online
- If there is no conflict with other redirecting rules
- Whether the service works properly within the local network
- Whether the router firewall or the device itself is not blocking the connection
Final considerations
Port redirection is an essential resource to extend remote access to local network devices. When properly configured and with security attention, it offers practicality and control without compromising network stability.
