End-to-end secure connection to the network is enabled by a PHP/MySQL backend that is responsible for handling user authentication, assigning dynamic IPs, and managing peer onboarding using a REST API. A peer monitoring dashboard along with firewall management capabilities gives live status of connections between clients and the central server, allowing the administrator to apply access control policies without requiring shell-level access. Secure access to the application is ensured by session-based authentication coupled with automatic token refresh, peer metadata storage in MongoDB, and separation of roles among admin and user portals. Experimental results show successful integration of peer onboarding and network segmentation using firewall rules along with real-time peer monitoring dashboard running at under one second refresh intervals.  \nKeywords: wireguard, vpn management, iptables, firewall, network security, peer monitoring, php, mongodb  \n1. Introduction  \nThe increasing popularity of remote working and distributed computing has led to a need for secure and managed Virtual Private Network (VPN) systems. Although current traditional implementations of VPNs are functional, their major drawbacks include difficult configuration, poor observability, and cumbersome operations. WireGuard is a relatively recent addition to existing implementations. Proposed by Donenfeld (2017), WireGuard boasts an efficient architecture with simple code, kernel-level performance and improved throughput in comparison to traditional protocols like OpenVPN and IPsec.  \nA large-scale administration of WireGuard involves not only its protocol features but also tools for managing peers, distributing dynamic IPs, enforcing firewall policies, and monitoring active connections. While there exist several commercial products addressing these concerns,  \nPublished: 02 June 2026  \nDOI: [https://doi.org/10.70558/IJST.2026.v3.i2.241270](https://doi.org/10.70558/IJST.2026.v3.i2.241270)  \nCopyright © 2026 The Author(s) .

SunduVault consists of a web-based PHP interface, two databases (MySQL and MongoDB), RESTful API for peer management, firewall management interface using iptables, and a WireGuard peer monitoring interface. Furthermore, SunduVault features two separate portal interfaces (admin portal and user portal), strict session-based authentication with automatic JWT refreshment, and WireGuard peer management automation.  \nOrganization of the rest of the paper is as follows. In Section 2 we give an overview of the related literature. System architecture is discussed in Section 3. Section 4 focuses on implementation. Experimental results are reported in Section 5. We conclude our paper in Section 6.  \n2. Literature Review  \nWireguard was defined by Donenfeld (2017) as a high-performance, low-configuration VPN solution based on the Noise protocol framework, key exchange using the Curve25519 algorithm, authenticated encryption using ChaCha20-Poly1305 and hashing using BLAKE2s. Various empirical analyses of network performance have confirmed the speed benefits of the technology compared to OpenVPN and IPsec (Osswald et al., 202","cbCaiadJFWN9Krda","https://ap.wps.com/l/cbCaiadJFWN9Krda","pdf",794347,10,"English","# 1.
