Use the CHR for protecting your cloud servers using RouterOS firewall which supports Layer7 filtering, dynamic address lists and more; for running your own VPN service or monitoring network infrastructure using The Dude! It can be used as simple to deploy HTTP proxy with domain name filtering, centralized RADIUS server for AAA (Authentication, Authorization and Accounting). CHR itself can be monitored using SNMP and monitor traffic using Traffic flow. CHR can function as a DNS cache and/or static DNS for a local network. Expand the local network using BCP (Bridge Control Protocol) bridging of tunnels. Use CHR as a platform for learning networking and RouterOS at your own pace, for testing configuration before deployment in production.
