SonicOS 7 Rules and Policies


  • Only two health-check mechanisms (ICMP ping and TCP socket open)
  • No higher-layer persistence mechanisms (Sticky IP only)
  • No “sorry-server” mechanism if all servers in group are not responding
  • No “round robin with persistence” mechanism
  • No “weighted round robin” mechanism
  • No method for detecting if resource is strained

While there is no limit to the number of internal resources that the SonicWall network security appliance can load-balance to and there is no limit to the number of hosts it can monitor, abnormally large load-balancing groups (25+ resources) may impact performance.
