What is ZeroShell?

ZeroShell is a Linux distribution used primarily on routers as well as embedded devices and servers. The objective of this operating system is to provide the main connectivity and network services to its users, such as DHCP, DNS, Firewall, VPN, WiFI, PPP service (3g/4g/5g modem), LDAP, etc.

Currently the ZeroShell project is discontinued and security updates for new vulnerabilities affecting this distribution are no longer provided, so migrating to other solutions such as OPNsense and PfSense is recommended.
