I have a new client with a restaurant and a currently unsecured network. It's basically a Comcast SMC business gateway four port w/ a bunch of wireless routers and switches hanging from it. Client is offering guest wireless from one router, and running a small network of office machines AND a point of sale network (which does not not process credit cards (doh!)) on another. Currently experiencing DNS/routing issues, poor performance, and obviously (to me) security issues.
My opinion is that the client needs three VLANed or segregated networks - one for office machines, one for POS, and one for guests. I'm looking for a robust, secure, and easy to manage solution for this client using his existing Comcast gateway. I've considered proposing a SonicWALL appliance, like a TZ 105 or TZ 205, but I'm unsure of the configuration options (i.e., can I configure three logical wired and wireless networks on this product?) Any better ideas? I'm hoping this is a discussion that can help many other folks, since I think it's a pretty common issue (i.e., retail, small business, medial office, etc.) Any and all suggestions, links, etc. would be appreciated.
