Hi George,

The ASA only supports a maximum DHCP pool size of 256:

http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/basic_dhcp.html#wp1125251

"If the number of hosts is unlimited, the maximum available DHCP pool is 256 addresses."

Does that mean 256 for BOTH the default basic inside LAN and the available DMZ, or 256 for EACH??

thank you Mirober and Alex for your replies

i have two inside LAN sides (guest and admin), for admin it's static IP but the problem with guest that i need to enable DHCP server to give them more than 1000 IP addresses

i have read from the documentation that i cannot create a DHCP pool for more than 254 ip addresses even if i have unlimited lisence

thank you
