Release Date: 25 September 2024

Release Date: 26 August 2024

Support Routing mode:

Port Base Routing: Allows routing based on specific ports for granular control of network traffic.
Support NAT (1:1, Port Forwarding, Masquerade)
- 1:1: Direct mapping between internal and external IPs.
- Port Forwarding: Redirects specific port traffic to internal IPs.
- Masquerade: Maps multiple local devices to a single public IP.
Support Static Routing: Manual configuration of routing paths for consistent and predictable network traffic.

DPI Enhancements:

Improve new UI:

Support Dashboard: Centralized view of device status, performance metrics, and security alerts.
Improving the settings page: More user-friendly with better organization and clearer configuration options.

DOS/DDOS prevention:

ICMP Protection: Filters malicious ICMP packets to prevent attacks like ping floods.
Null Scan Filter Function: Blocks null scan attacks by filtering packets with no flags set.
Xmas Filter Function: Prevents Xmas scan attacks by blocking packets with FIN, URG, and PSH flags set.
SYN/FIN Filter Function: Detects and blocks SYN/FIN scan attacks.
TCP Offset Protection Function: Ensures TCP packets have valid offsets to prevent manipulation.
Min. Header Size Filter Function: Blocks packets below the minimum TCP header size to prevent attacks with malformed packets.

Support OTAccess Integration.
