Hi, What should i do if some user get disconnected but don't get their ip again. I've set up allocation 1 ip to that user, but when get disconnected did not get the correct ip, in fact the user get another ip. It seems that the ip still active on radippool table, i have set up lease time for 300 second. Is there any clue how to fixed up this ? I give log from this issue. Thanky you in advanced.
