Using SAS4 IP Pools

Follow these steps to let SAS Radius assign IP addresses itself.

  1. Create the pool in IP Pools (see IP Pools).
  2. Edit the profile (Profiles → profiles list), set IP Pool Mode to Use SAS4 IP Pools and choose the pool in SAS4 Pool Name. Save.
  3. Route the range to your network: the addresses must be routed to the routers, and NAT (masquerade) or public routing must be configured for the range, exactly as for a router pool.
  4. Users get an address from the pool at their next connection. Disconnect online users if they must change now.

Tips

  • Use different pools for different packages or for expired users, so you can apply firewall and routing rules per pool on the router.
  • Users with a Static IP keep their static address unless the profile has Ignore Static IP ON.
  • The router-side Pool Name in the NAS form overrides profile pools for all users of that router; leave it empty.
  • For Use NAS IP Pools, the Pool Name in the profile must exist on every router, with exactly the same name (case-sensitive).

The IP Pool Mode and Pool Name fields are also described on the Profile Form page.
