Hallo I have the following situation: pool ip's are allocated correctly, but after the lease-duration is reached, they are deleted from the radippool table. This causes the ip to be once again assigned to another user, who in turn requires a new login, since this ip won't work I have tried to enforce a "keep-alive" with acct-interim, but it doesn't work, the ip's are deleted from radippool when the lease time is up ? how can I prevent this ? Thanks, petre root@core-router:/etc/freeradius# radtest -x petreb petreb localhost 1980 radiuspass Sending Access-Request of id 7 to 127.0.0.1 port 1812 User-Name = "petreb" User-Password = "petreb" NAS-IP-Address = 1.1.1.1 NAS-Port = 1980 rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=7, length=38 Acct-Interim-Interval = 120 Session-Timeout = 1195235 Framed-IP-Address = 1.1.1.2
