The Server page lets you monitor and control virtual servers and services that are present on the Barracuda NG Firewall. To access the Server page, open the Control tab and click the Server icon in the ribbon bar.
The Server Status table displays the status of all available servers. You can see the following information about the virtual servers that have been introduced on your Barracuda NG Firewall:
- Server – Lists all servers and their status, HA partner (optional), and IP in a hierarchical tree. Under the IP node, each defined server IP is listed. Icons indicate the current status of each server:
- Green – Server is up.
- Yellow – Server is blocked.
- Red – Server is stopped.
- Grey X – Server is disabled.
- Status / Status HA Partner – The Status column displays the status of the server. If the system is part of an HA cluster, the Status HA Partner column displays the status of its HA partner. The columns can display any of the following statuses:
- primary – Server is up and running, either as a single system or as the primary unit in an HA setup.
- secondary – Server is up and running on the backup unit of an HA setup.
- standby – Server is in standby and is waiting to take over if the HA partner goes down.
- down – Server is not running, but is able to start automatically when triggered.
block – Server is blocked and unable to start automatically, even if the HA partner goes down.
disabled – Server is disabled due to environmental conditions, such as when the monitoring IP or monitoring interface is not available.
IP Addresses – Lists the IP addresses that the server listens on.
To start or stop a virtual server, click it in the Server Status table (you can also right-click the server) and then select one of the options listed below the table.
The Service Status table displays the status of available services. You can view the following information about the services that have been introduced on your system:
