How can I exclude certain IPs from an DHCP Pool?
In Windows SBS2003 DHCP, I can reserved some IPs..How can I do that in Mikrotik?
Thanks!

Make them static without a real mac address so they never get assigned to anyone.

Or, build your pools around them. Pool1=192.168.0.101-110 Pool2=192.168.0.121-131

Do I select IP > DHCP Server > Leases
-Pick the IP I want & ‘Make Static’???
How do I make it static without MAC Address?
Thanks!
