Clear DHCP assigned addresses

[TalentedFool]

Is there a way on the PIX 515 to clear the IP addresses that have been assigned to users via DHCP?

I've set the timeout on the lease to be 43200 second which I think is 24hours, but I've have 10-15 IP addresses just renew their leases. I know they're not on the network cause I can scan the IP's on my net and they're not in use!

I can use "sh dhcpd bind" to show them but is there a clear or remove command?

Thanks

HI.

One day is 86400 seconds (3600*24).

You can try using the "capture" command to collect more info (like a network sniffer):

My suggestion however is to use a different DHCP machine. W2K server has a better DHCP server which is also easier to manage. All other current server OS (linux, netware, etc) has DHCP so why not use it.
I think that using DHCPD on pix is good only if you don't have other options like SOHO with workgroup only.

I think I will be going to Windows when I get our 2003server set-up ready for use.

Thanks.
