To apply changes in this section, click the **Apply** button. Use the **Revert Changes** button to discard modifications and revert to the previously applied configuration. ### HTTP Web GUI Service This service is used for administrative and operational management purposes. The HTTP service delivers the web GUI. [![relianoid load balancer v8 system services http](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_http.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_http.webp) **The physical interface where the GUI service is running**. The interface where the GUI service is running, bound to all physical, bonding, and VLAN interfaces configured in the load balancer. Note: Virtual and floating interfaces are not recommended. **HTTPS Port where the GUI service is running**. Port used by the web GUI service for administrative and operational purposes. The default port is **444**. **Server Certificate**. The authentication certificate that shows a user has permission to use RELIANOID appliances. After pressing the **Apply** button, you will need to confirm the changes in a popup. ### SSH Management Service This service is used for maintenance and clustering replication purposes, allowing remote command line access to the load balancer. [![relianoid load balancer v8 system services ssh](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_ssh.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_ssh.webp) **The physical interface where the SSH service is running**. The interface where the SSH service is running, bound to all NIC, bonding, and VLAN interfaces configured in the load balancer. Virtual and floating interfaces are not recommended. **SSH Port(s) where the SSH is running**. The port used by SSH services. The default port is **22**. Press the **Apply** button to apply changes to the Interface and Port settings. The SSH service will be restarted. ### SNMP Monitoring Service This service is used for load balance monitoring and integration into a centralized SIEM platform. [![relianoid load balancer v8 system services snmp](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_snmp.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_snmp.webp) **Enable SNMP**. Enable or disable the SNMP service. It is disabled by default. **Physical interface where the SNMP service is running**. The interface where the SNMP service will run. **SNMP Port where is running SNMP service**. Port where the SNMP service will listen. The default port is **161**. **Community name**. The read-only community name to be used. The default is **public**. **IP or subnet with access (IP/bit)**. Clients' subnets or addresses allowed to access the SNMP service. For a single IP address, use the netmask bit **/32**. The **Apply** button will apply all changes to the SNMP service. For more about SNMP, read our article on [Understanding SNMP in a SIEM environment and Monitoring RELIANOID Appliance](https://www.relianoid.com/resources/knowledge-base/howtos/understanding-snmp-in-a-siem-environment-and-monitoring-zevenet-appliance/). ### Rsyslog Logging Service [![relianoid load balancer v8 system services rsyslog](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_rsyslog.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_rsyslog.webp) **IP/Hostname**. The name of the Rsyslog host. **Port**. The port for sending log files. **Protocol**. The transmission protocol, either UDP or TCP. The **Apply** button will apply all changes to the Rsyslog service. ### Global Services These services modify a system to adapt any load balancer to the client's needs. [![relianoid load balancer v8 system services global](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_global.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_global.webp) **Enable session replication**. Replicates session tables to the backup node if a farm is configured with persistence. This feature is part of the **Stateful Cluster**. Enabled by default. **Enabled duplicated network**. Allows the establishment of the same network twice, which is not supported by the RELIANOID Routing system. Disabled by default. **Enable ARP announce**. Executes an ARP announcement to the network for MAC changes. If enabled, an announcement is made each minute. Disabled by default. **Enable WAF assistant**. Enables the OWASP Core Ruleset to be loaded as a application firewall interface to protect and monitor the HTTP protocol. Click the **Apply** button to apply all changes to the **Global Services**. ## Remote Services The **Remote Services** section manages external services needed by the load balancer, such as **DNS** for network name resolution, **NTP** for system clock synchronization, and the **Proxy** service for using an external proxy for internal services. To apply changes in this section, click the **Apply** button. Use the **Revert Changes** button to discard modifications and revert to the previously applied configuration. ### DNS Service The Domain Name System service resolves domain names to network addresses. Servers configured for DNS resolution will be stored in the system file **/etc/resolve.conf** . [![relianoid load balancer v8 system services dns](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_dns.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_dns.webp) **Primary Server**. The IP address of the primary name server. The default value is **8.8.8.8**. **Secondary Server**. The IP address of the secondary name server. This value is optional and blank by default. ### NTP service This service synchronizes the load balancer's system date and time clock. [![relianoid load balancer v8 system services ntp](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_ntp.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_ntp.webp) **NTP Server**. The server IP address or domain name for synchronizing the system date and time. The default value is **pool.ntp.org**. ### Proxy Service This service allows the load balancer to access the Internet through a remote proxy. Some services, like updates, use this option if configured. [![relianoid load balancer v8 system services proxy](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_proxy.webp)](https://static.relianoid.com/wp-content/uploads/2024/06/relianoid_EE8_system_services_proxy.webp) **HTTP Proxy**. Define the full URL of an HTTP proxy for HTTP requests, e.g., **http://myproxy:80** . **HTTPS Proxy**. Define the full URL of an HTTPS proxy for HTTPS requests, e.g., **http://myproxy:443** . ## Let's Encrypt This certificate proves a server's authenticity and provides secure data transmission through encryption.
