Configuration
Can I use a load balancing method other than Round Robin?
By default, STACKIT Network Load Balancer uses the Round Robin method. If you enable session persistence on your target pool (for example, in the Portal UI or via the API by setting
session_persistence.use_source_ip_address=true), the method changes to Maglev.Can I configure multiple listeners or ports?
