It would help greatly to have a network topology. Are you going to need Wireless for your private network? You might beable to set the SRW to layer 3 mode and do inter-vlan routing and use ACL's to block certain traffic, but to give you a step by step configuration we would need more information.
It dosn't look like that AP has VLAN or Trunking support, you most will not be able to have both guests and local users on the same AP and block only the guests from the local LAN without the AP sporting Trunking or VLAN's
I would recommend a AP that can do Multiple SSID's and Trunking.
Having a VLANable WAP such as the older WAP4410N or even the newer WAP121 or WAP321 or AP541 will get network segmentation out to the switch egress port that leads to the WRT610N . BUT NOT TO THE WRT610N
I do not believe the WRT610N is VLAN capable with native firmware. This is part of the problem.
To achieve what you want , you also need to use;
A VLAN-able router such as maybe the RV180 or RV180Wor RV220W SA500 or ISR881 etc.. All these routers are VLAN capable and will supply a different DHCP scopes to the seperate VLANs.
A VLAN-able WAP as mentioned before
Your current SRW2024 switch
You can the use your older SRW2024 switch ( replaced by SG300 series ordering p/n SRW2024-K9 ) to provide ACL functionality to restrict access between the guest network and the corporate network.
hope this helps, maybe not the answer you wanted to hear. If someone has a better one please dive in.
A couple of ways to put a switch into layer 3 mode, as per the admin guide..
The built in menu is the easiest way of performing that task. It can be accessed via the console cable or via enabling the telnet service on the switch, via the GUI. (As a security precaution, telnet is disabled on the switch by default)
Step 1. Type 'menu' from the Textview CLI interface, to get to the switch main menu. Select the system mode option.
Step 2. edit the information to change the switch mode from layer 2 to layer 3 mode.
But Swapnil, this will create another issue for you, as you will have multiple IP networks on the LAN switch. But you to still supply DHCP services to this extra IP network, the guest VLAN.
I don't believe that the WRT610N with it's default firmware will support multiple DHCP scopes or respond to a DHCP relay request from the SRW2024-K9..
Still think you need a VLAN aware WAN router that supports multiple VLANs.
