We have already seen how Umbrella works in previous posts and now let's do the basic configuration.
https://www.stenge.info/post/umbrella-va
Configuration Mode on a VA Deployed:
When you open the VA in your preferred hypervisor's console, and you'll see a configuration menu. As seen in the lower right corner, the system time is set to UTC by default. This will not affect your DNS, network, or hypervisor.
To access the VA console efficiently, use a native application (such as VMware vSphere Client, VMware Remote Console, or RDP)
If you have deployed the VA in a network that supports DHCP, the VA is automatically assigned a DHCP IP address and registers to Umbrella using this IP. This IP address appears on the configuration as well as the Umbrella dashboard.
1- Press Ctrl+B and when prompted, provide a password for configuration changes;
Note: Umbrella<OrgID> should be set as the default password for the VA. Your Org ID can be retrieved from the dashboard URL in your address bar.
2- Optionally, enable remote configuration of this VA over SSH, enter config va ssh enable;
3- If you have enabled SSH, you can now remotely connect to the VA over SSH and enter Configuration Mode after authentication. use vmadmin as your login.
Note: Configuration mode does not support concurrent access by more than two users.
Configure the VA Through Configuration Mode:
☂ Configure the name:
config va name <hostname>
☂ Configure the IP, Netmask, and Gateway:
config va interface <ipaddress> <netmask> <gateway>
☂ Configure an IPv6 address:
config va interface6 <ipv6 address>/<prefix> <ipv6-gateway>
☂ Configure SNMP:
config snmp configure -v2 c <community>
☂ Configure NTP:
config ntp add <ipaddress>
☂ Configure local DNS:
config localdns add <ipaddress>
☂ Configure Rate-limiting:
config va per-ip-rate-limit enable <pps> <burst>
☂ Configure Umbrella Resolvers:
*By default, the VA is configured to use the standard Umbrella resolvers (208.67.220.220 and 208.67.222.22)
config va resolvers alternate
☂ Configure DNSSEC Support:
config va dnssec enable
☂ Logging to Remote Syslog Server:
