Home lab routing issue

[JasonE1977]

I'm a bit of a novice when it comes to networking, so please excuse my ignorance.

I have a Linksys WRT54GS wireless router (10.77.79.1, 255.255.255.0) which hands-out DHCP addresses to my wireless/wired clients.  This router is connected to the cable modem which then connects to the wonderful World Wide Web.  Port 1 of this router is connected to a Cisco SG200-8 Small Business Switch (10.77.79.3, 255.255.255.0).  My Dell 2950 is then connected to the SG200-8.

I would like to segment my lab environment (Dell 2950) using a 192.168.10.X scheme, so I configured a static route in the WRT54GS using these settings:

Dest. IP: 192.168.10.0

Mask: 255.255.255.0

Gateway: 10.77.79.3

Here is my IP information for the SG200-8:

IP: 10.77.79.3

Mask:  255.255.255.0

Gateway:  10.77.79.1

I know I'm doing something wrong because I cannot ping any of the 192.168.10.X IP addresses from the 10.77.79.X network, and vice-versa.

All VLANs on the SG200-8 are set at their defaults (1 and Trunked?).

Are there any additional configuration steps I need to perform in the SG200-8 or WRT54G?

Is what I want to do even possible with my hardware?

Any help is appreciated.

Thanks,

jason

Hello Jason - wrong section, can you kindly move this discussion to the small business routers/switches forum please. You can do this from the right hand side of your post.

Just wanted to mention you might need a vlan? Or a static on the Cisco SG200 to specify where the 192.168.x.x lives.

Thanks

Hi Jason, one problem is the Sg200 is a layer 2 switch. It does not have any routed interfaces, it is for management only. If your goal is to manage that switch while it's on a different subnet, the only requiremt would be setting a default gateway on the switch pointing to the layer 3 device that will route the traffic for the specified subnets.

Thanks for the response Tom. Right now the SG200 is on the same subnet as the wireless router, so management isn't an issue there.  My goal is to have everything else that is connected to the SG200 be on a different subnet (192.168.100.0) and still be reachable from the 10.77.79.0 subnet.  Maybe I'm missing something or maybe this is beyond the capabilities of the SG200.

Thanks again,

jason

Hi Jason, the sg200 switch is only layer 2, It is incapable of routing between vlans and subnets. The router (or routing device) would have to do this for you.
