Protected ports, multiple routers

Hello -

I'd like to take advantage of the 'protected port' feature of my SG 300 and SG 10 switches, but it seems that the isolation offered only works with devices within the switch - i.e. it does not isolate the port against the switch that the switch is connected to.

Here's my setup.

    wireless AP

(to be isolated)

            |

   10p Switch B  10p Switch C   10p Switch D

             |                   |                   |

============== 28p Switch A==============

                                |

                            Router

                                |

                           Internet

The wireless access point needs to be isolated, presumably with a protected port. The protexted port does isolate against everything in Switch B, but anything connected to Switch A is still accessible. Is there any way, using protected ports, to extend this functionality without isolating every other device connected to Switch B?

Thanks!

Protected ports, multiple routers

What are you trying to accomplish?

If you don't want wireless users to have access to devices on the network, this is usually done via assigning wireless users to a dedicated VLAN and applying an access-list to the Layer 3 gateway that services that VLAN.

Here are some "how-to" links:

Setting up Guest WLANs

Setting up restricted access to protect internal resources
