List of the Top 5 On-Prem Virtual Routers in 2025

ARPMiner features a graphical user interface (GUI) alongside a service known as TekSpot, supporting protocols such as PPPoE and HTTP, in addition to providing a DHCP server and a proxy DNS server. The SP edition is the only version that includes support for RADIUS accounting and encryption for PPP connections. Users can manage access control through three different modes: Network Address Translation (NAT), Bridge mode, and PPPoE Server mode. Within ARPMiner, it is possible to configure the private interface's IP address and subnet mask directly from the management interface. When settings are saved within ARPMiner, the interface's IP address and subnet mask are updated at the operating-system level. Furthermore, the Sponsored Authorization feature allows HotSpot Users to seek access through an email request directed to a corporate employee. In this process, ARPMiner facilitates sending an access request via email to a designated sponsor email address provided by the user. For additional details, users are encouraged to consult the Sponsored Authorization section of the ARPMiner Manual, which offers comprehensive guidelines. Moreover, this functionality enhances the user experience by streamlining access requests in a corporate environment.
