Cisco ASA 5505 Guest VLAN

Hi Experts,

I have a Cisco Aironet and a specific SSID for guest users. I'm going to assign a VLAN to this SSID and I'd like any users that connect to it to only have access to the Internet....Not the internal network. Being a Cisco novice, how do I do this through ASDM ? Help is much appreciated. Thanks.

If you have the base license you need to restrict access from the inside network to the wifi network as the license only allows for a "restricted DMZ".

If you want to do this from the gui I whish you a lot of luck, from the console/ssh/telnet you can use this:

# If using a base license we need to use DMZ Restricted
# disable forwarding traffic from inside (vlan1) to dmz (vlan3)
interface Vlan1
no forward interface vlan 3
# Create DMZ interface
interface Vlan3
 nameif dmz
 security-level 50
 ip address 172.16.25.254 255.255.255.0
# Assign Ethernet 0/2 to DMZ
interface Ethernet0/2
 description DMZ
 switchport access vlan 3
 no shutdown
# configure a DHCP server for the DMZ clients
dhcpd address 172.16.25.100-172.16.25.199 dmz
dhcpd dns 8.8.8.8 8.8.4.4 interface dmz
dhcpd enable dmz
# NAT for IPv4
object network IPv4_DMZ_NETWORK
 subnet 172.16.25.0 255.255.255.0
nat (dmz,outside) after-auto source dynamic IPv4_DMZ_NETWORK interface
# IPv4 access rules to the internet from the DMZ network
access-list dmz_access_in extended permit icmp any any
access-list dmz_access_in extended permit udp any any eq domain
access-list dmz_access_in extended permit tcp any any eq domain
access-list dmz_access_in extended permit tcp any any eq http
access-list dmz_access_in extended permit tcp any any eq https
access-group dmz_access_in in interface dmz
