captive portal logout page
We made a portal for usage for staff login in lan network. the captive portal is accessed by local users. the captive portal is working and able to login but after that there is no logout page. As the local users are allosed use for 3 months together, they are not logging out after disconnecting. after disconnecting next day also it is still logged in by a single user. for the second user to login there is no logout page for first user. there is default portal address is given (portal.tplink.net/portal/logout- it is not working. My lan is controlled by OC200 hardware controller
Please direct as how to logout from captive portal.
