I’m wondering if it is possible for the mikrotik dhcp server to send out a force-renew message to clients so I they can get a new ip address instead of waiting for their current lease to expire or trying to contact the customer and guiding them through an ip renewal process. If possible then how?
Hi.
When you create the DHCP server, you can put Lease time to 00:00:01.

wouldn’t that create problems with everyone’s computer/router renewing their leases every 1 second?
As far as I know there is no way to force a client to renew their IP address from the server. You can set the lease time to a shorter time, but 1 sec is too short since the client tries to renew at 1/2 the lease time then like 3/4 or 7/8 of the lease time which needless to say will create a lot of traffic. You can also set it shorter temporarily and as client renew their IPs they will get the shorter lease time.

I think this lease time is the time that the server give’s you the same address if you disconnect and reconnect to wlan. You can put 3 or 4 if you like. If you don’t disconnect you will have the same address…

I had a problems with some devices like Canon printers when lease time was set to 15 min. My advise not to use shorter than 30 minutes time.
