How to restrict the traffic from different network?

Please see the network setup for 2 different network sites. A network site is the HQ, and it has a direct Internet access via a firewall. B network site is a branch and it doesn't have any Internet line. Both sites joined to the same Megapop private network for network communications. Now, users in B network can access Internet via the Megapop private network and using the firewall located in A network. Users in B network also can access the 2 servers plus other accessories, such as, network printers.

Now, a wireless AP is deployed in B network, and IPs are allocated to the wireless clients using AP's DHCP with the range as stated. Can I restrict in such a way that wireless clients with IPs allocated by this AP are not allowed to Server A and Server B located at A network, what should I do?

The easiest way would be to define a VLAN for the wireless network and then apply an ACL that would block wireless traffic going to servers A and B.

Is that an option?

Or do the wireless users have to be on the same IP network as the branch wired users?

Hi Don,

Too bad, vlan is out of the option. All have to be on same ip network.

From the HP site:

The HP 1420 Switch Series consists of unmanaged Gigabit Ethernet switches

There is no way to control or limit traffic on an unmanaged switch.

Expert Don pointed the important point - 1420 is an unmanaged switch that does not support VLANs. So, there is no way to segregate traffic before blocking them.
