Is is possible to alter the lease time for DHCP?

I am running a DHCP server for an open WiFi area, and it would be nice to get a rough idea of usuage by looking at the DHCP assignments.

At the moment, a person can aquire an IP Address, use the internet for a couple of minutes, and then never return. The DHCP assignement remains for a fair while though.

You can set the lease time through telnet. For example to set lease time to an hour (3600 seconds), the last line is a check to see if it has applied.

At a command prompt:

telnet

srv set leasetime 3600

srv set leasetime ?

Bump, Bump, Bumpaty Bump!

Sorry, forget I even posted this!

I have tried this command through telnet and it says the command is unknown?

This is the Vigor 2800G?

Will these changes be persisted over a reboot ?

I havent tested this specific setting but I dont see why it shouldnt. Other telnet only settings do that I have used.
