Linksys SRW224 VLAN

[rpaverd]

I have a temporary requirement for a shared broadband connection. The objective is to have a single inbound broadband connection (probably DSL coming in via a Linksys router) shared between 3 or 4 separate business.

Obviously from a business perspective each business should have their own private address range.

Using the VLAN facilities of the SRW224 is it possible to provide each business entity with their own private subnet range on a specific port or ports on the SRW224? None will require more than 4 or 5 PCs in their network....

Any suggestions welcomed...

rpaverd,

The SRW224 can do that. Just use the web interface to set the links to the desired VLANs. You will need to trunk the uplink to the router and the router will also have to support VLANs. I believe the pix 506e Version 6.3(5) will support 3-4 VLANs. I am not sure about the 501.

Thanks for the response.

I am confused, however.... I cannot find any basic references to, or examples of setting up VLANs on the SRW224. Does anyone out there have any?

From your response it appears that you require a high-end router/firewall to support the VLANs. Can I use a standard Linksys router and add routes in the static routing facility?

Alternatively, would it not be easiest just to simply get four Linksys routers, use one as the gateway and the other three to route traffic from the other three networks?

As always - all responses are much appreciated.

Thanks again

Richard

Here is a link to the product page for that switch

http://www.linksys.com/servlet/Sate...180432&pagename=Linksys/Common/VisitorWrapper

The userguide has the VLAN setup info on page 38. You just set up the VLANs on that page and on the port page, you assign the ports to the desired VLANs.

You can use a lower end router/firewall. I just default to PIX. The Linksys RV082 (~$250) supports up to 8 VLANs and has VPN as well. That should be a good bit cheaper than the PIX. The problem with base level consumer routers is that they don't support VLANs. The frame gets an extra 4 bytes with 802.1q and devices that don't support it will drop the packet.

You can get multiple routers and set it up that way but since things get NATed twice, troubleshooting is such a hassle. Besides, VLAN's are a little more elegant and it's always worth it to learn more.

In other words, Read The F(riendly) Manual!

My apologies. Often I have said that to others and yet I have fallen into the same trap...

Thank you.

I believe that the Pix 506 only supports two VLANs (maximum of 4 interfaces) so will look closely at the RV082.

For this specific project I have, however, arranged for a range of static IPs, so it is easiest for each business just to have their own router - gives them the 4 ports they need as well as each of these will be separately located at the venue.

Thanks again
