IP Pools

Every subscriber needs an IP address when connecting. SAS Radius supports two ways to assign addresses, chosen per profile with IP Pool Mode:

IP Pool Mode Who assigns the IP When to use Use NAS IP Pools (default) The router. SAS Radius only sends the Pool Name; the pool must exist on the router with the same name. Most networks, especially with one router or pools that differ per router. Use SAS4 IP Pools SAS Radius, from pools created in IP Pools. The router receives the exact IP for each user. To manage all address ranges in one place instead of on every router.

Start IP First address of the range, for example 10.20.0.1. End IP End of the range, for example 10.20.3.255. It must be after the Start IP. The pool contains the addresses from Start IP up to, but not including, End IP.
  • Large ranges take a little longer to save, because every address is prepared.
  • Editing a pool rebuilds its address list.
  • Deleting a pool also removes it from all profiles that use it; those profiles go back to Use NAS IP Pools.
