    CacheGuard Gateway

    CacheGuard Gateway

    CacheGuard Gateway is a UTM, a WAF, and a QoS management appliance.

    CacheGuard Gateway is a free and open-source Unified Threat Management (UTM) solution, a Web Application Firewall (WAF), and a Quality of Service (QoS) platform designed to optimize WAN traffic. To obtain a CacheGuard Gateway appliance, download CacheGuard-OS and install it on the bare-metal or virtual machine of your choice. It’s that simple and completely free. The UTM includes a firewall, web antivirus, VPN server, and a URL-filtering and SSL-inspection web proxy. The WAF operates in conjunction with a reverse proxy, web application load balancer, and SSL offloader, and is capable of blocking malicious requests as well as traffic from IP addresses with poor reputations. The QoS manager enables traffic shaping to prioritize critical network flows, load balance multiple WAN links, and cache web traffic.

    OpenVPN for Windows XP

    OpenVPN v2.5.4 patched for Windows XP and Windows Server 2003

    OpenVPN v2.3.18 was the last version that officially supports Windows XP and Windows Server 2003. We lately had the need to use the newer version 2.5.4 of OpenVPN to support stronger data ciphers like AES-256-CBC. Therefore we decided to rebuild the whole package from the ground up to make it compatible with Windows XP and Windows Server 2003. The following article describes in detail how you can rebuild OpenVPN v2.5.4 for use on these older operating systems. The benefits of this new version include: - support of stronger data ciphers like AES-256-CBC - new TAP-Driver with a network speed of 1 GBit/s instead of 10 MBit/s - severe bug on Windows XP SP3 solved where we can't connect to the VPN server For more details visit https://openvpn-for-windows-xp.sourceforge.io/
