I got a Cisco ASA 5505 (8.4) , I got a Wap 200 sitting on a port as an AP.
Sometimes (wireless) computers getting IP's from the ASA DHCP server cant get on the internet.
Configuration looks like this:
dhcp-client client-id interface outside dhcpd address 192.168.1.9-192.168.1.40 inside dhcpd dns 18.104.22.168 22.214.171.124 interface inside dhcpd auto_config outside interface inside dhcpd update dns interface inside dhcpd option 3 ip 192.168.1.1 interface inside dhcpd enable inside
Worth mentioning is that internal computers can always be reached.
