Manually Configuring HP Wireless (MSM 720 controller) for Public and Private Wireless Networks


KB ID 0000833 Dtd 17/07/13


In the following procedure I'll configure the following;

  1. HP 5412zl Switch.
  2. Cisco ASA 5510 Firewall.
  3. HP MSM720 Controller.
  4. HP MSM460 and MSM317 Access Points.

If you are configuring an MSM765zl or MSM775zl use the following article first.

HP MSM765zl and 775zl - Initial Setup and Routing


  1. Private SSID will be on the normal corporate LAN (In this case
  2. Public SSID will get its IP addressing from the controllers DHCP Server. (
  3. The Wireless traffic will traverse the corporate LAN (After being natted on the controller) as
  4. My LAN DNS Servers are and


HP Switch Configuration.

1. The switch must be performing LAN routing, if the LAN's default gateway is a firewall that needs rectifying first. (where is the firewall).

ip routing  ip route


2. Switch must be able to resolve DNS queries.

ip dns server-address priority 1


3. Declare a VLAN for the guest VLAN (210), name it, and give it an IP address > Add a Port (A1) to that VLAN which will connect to the Internet Port of the MSM Controller (Port5).

vlan 210  name WIRELESS-TRAFFIC  ip address  untagged A1


4. Tag This VLAN on the 'Inter Switch' Links from the core switch to the firewall/perimeter device.

tag D24


5. Save the Switch changes with a write mem command.


Configure the Cisco ASA To Allow the Wireless Traffic out.

Actions for different firewall vendors will vary but you need to achieve the following;

Make sure that a client on the network can get access to the Internet

To do that you will need to achieve the following;

Make sure that the network has http and https access allowed outbound on the firewall.  Make sure that is getting NATTED through the firewall to the public IP address.

1. Connect to the firewall > Allow the Wireless Traffic out.

access-list outbound extended permit ip any

Note: this permits ALL IP traffic you might prefer

access-list outbound extended permit ip any eq http  access-list outbound extended permit ip any eq https

Note2: This also assumes you have an ACL called outbound applied to traffic that is destined outbound (show run access-group will tell you)


2. Perform NAT on the new wireless outbound traffic.

object network WLAN-CLIENTS  subnet  nat (inside,outside) dynamic interface

Note: For Firewalls running versions older than 8.3 the NAT commands will be different, e.g.

nat (inside) 1

{Where you have a matching global (outside) 1 command in the config already}


3. Allow the firewall to 'route' traffic back to the wireless clients. (where is the core switch performing LAN routing).

route inside


4. Save the changes.


5. At this point plug a PC/Laptop into the core switch (Port A1) and make sure you can get Internet access ('you will need a static IP on the range).


Configure the HP MSM 720 Controller

MSM 720 Initial Setup and IP Addressing.

1. Connect to to the MSM 720 controller (Port 1) (username admin, password admin).

2. Go though the initial setup > Stop when you get to the Automated workflows screen (simply press Home).

3. Setup Access Network: Home > Network > Access Network > Set the Addressing and Management IP addresses like so;

  • Addressing
  • Management address



Note: There's two because you can separate the management traffic off to another subnet if you wish.

4. Connect Port 1 on the MSM controller to ANY normal port on the Switch (which will be untagged in VLAN 1) >Then connect to the Controller on its new IP

5. Setup Internet Network: Home > Network > Internet Network > Static.


6. Configure > IP = > Address Mask > Save (don't worry if you get a warning about DNS).


7. Connect Port 5 on the MSM to Port A1 on the switch (the one you untagged in VLAN 210).


8. Setup DNS: Home > Network > DNS > Enter the Primary LAN DNS servers ( and

9. Tick DNS Cache > Tick DNS Switch over > Tick DNS interception > Save.


10. Setup Default Route: Home > Network > IP Routes > Add.

11. Enter with a Metric of 1 > Add.


12. Setup DHCP (Note: you will create the scope later)

Obviously only complete this step if you want the Controller to act as a DHCP server for your 'Public' Wireless network.

Home> Network > Address allocation > Tick DHCP Server > Configure.


13. Enter the domain name > change Lease tome to 1500.

Note: At this point it automatically fills in DHCP Settings (these will NOT be used don't panic!)

14. REMOVE the tick form Listen for DHCP Requests on 'Access Network'

15. MAKE SURE there is a tick in the 'Client data tunnel' box > Save.


HP MSM 720 Configure Wireless Access Public and Private

For this procedure we will rename the default VSC which is called HP.

1. Home > Controller (on the left) > VSCs) > HP > Change the Profile name for HP to "Private" > Untick Authentication > Untick Access control.

2. Change the SSID from HP to 'Private' > Tick Broadcast Filtering.


3. Ensure Wireless security filters is unticked.


4. Tick Wireless Protection > Set the mode to WPA2 (AES/CCMP) > Change Key Source to 'Preshared Key' > Enter and confirm the WPA Password > Save (at the bottom of the screen).


5. Setup Public/Guest VSC: Home > VSC's > Add New VSC Profile.


6. Set the profile name to 'Public' > MAKE SURE authentication and access control ARE ticked.

7. Change the SSID to Public > Tick broadcast filtering.


8. Change Allow Traffic between wireless clients to NO > Expand Client Data Tunnel > Tick 'always tunnel client traffic'.


9. Ensure Wireless Protection is unticked.


10. If you require HTML based logins, tick that (Note: You will need to create a user later, if you enable this).


11. If using the controller for DHCP > Enable the DHCP Server and specify;

  • DNS
  • Start
  • End
  • Gateway
  • Net mask
  • Subnet


Create a Network Profile for Each of the New VSC's

1. Home > Network > Network Profiles > Add New Profile.


2. Call it 'Private' Tick VLAN ID select 1 > Save.


3. Add New Profile > Call it 'Public' > Tick VLAN ID and set it to 210 > Save.


4. At this point, connect your wireless AP's to the network, and the controller should detect them.


Bind the VSC's to the Default AP Group (Using the network profiles we just created)

1. On the left hand menu > Controller > Controlled Alps > Default Group > VSC Bindings (top) > Select the 'Private' VSC Binding.

2. Make sure 'Egress Network' is NOT ticked and none is selected > Save.


3. Add New Binding > Select the 'Public' VSC Profile > Tick EGRESS NETWORK > Set the Network profile to 'Public (210)' > Save.


Create user accounts (Only if using HTML Based Authentication)

1. Home > Users > User Accounts > Add New Account > specify a name i.e guest > specify and confirm a password i.e. Password123.


2. Change the MAX concurrent Sessions to 250 > Enable VSC Usage > Add the 'Public' VSC (right arrow) > Save.


Synchronize the Access Points to the MSM Controller

1. Home > Controller (left) > Controller APs > Overview Tab > Change the Action drop down to Synchronize Configuration > Apply.


2. Wait for the APs to synchronize > Test both the SSIDs.
