I am looking to provide an appropiate solution for a client who has four(4) offices that need to connect to the main office. Office A where all files are located has a full T-1. Office B,C,D have DSL. Office A) Has 42 Employees who acces the internet and email and all network shares. Office B has 8 employees who access the internet an email plus need access to the files from Office A. Office C 4 employees accessing Internet and email also needing access to files from Office A. Office D only has only 2 employees with internet and email who also need access to the files at Office A. They currently have 3 com Office Connect's that no longer function properly. They are interested in a cheap solution and have shown intrest in the Linksys Brand. I understand Office a will be 192.168.1.1 Office B 192.168.2.1 Office C 192.168.3.1 Office D 192.168.4.1 all on the 255.255.255.0 subnet. What i'd like is recommendation on router/firewall equpment. and something more specific on the 192.168.*.* thing, just in case i have it wrong.

Hi izombie73,
Personally I would not go for Linksys or any other home user brand as they are not really stable enough for corporate use and you don't get the control you may need at a later date. I would look at products such as Sonicwall, Watchguard or Cisco PIX.
If you were to go the PIX route you could use a 501 for the remote offices and either a 515 or a 506 for the main office.

Thanks for the suggestions grblades. I checked into the Cisco equipment. Nice Stuff. The only problem is the cost is still to high. I know this client would probably go for something like the D-Link 804hv. They have said that another company they know with a similar setup uses cheap Linksys firewall/routers. This is all fine and good, the problem is they do not have a computer admin not at Office A or the sub sites. If the linksys go down then the vpn goes down. Then I have to fly to the 3 sub offices. Oh what fun. Is there any of the cheaper stuff that is any good and that will work.

If you go for a cheap product I would stick with a single make and model to try and avoid problems.
You will need a product which supports at least 3 VPN sessions at the main office. I would advise that you also get such a product for the remote offices aswell incase in the future you need communication directly between offices.

On the Linksys range there is the BEFVP41 (http://www.linksys.com/products/product.asp?grid=34&scid=29&prid=607) which can handle 50 VPN connections. This model has been around for a while so any bugs in the firmware should have been fixed.
There is the new RV042 (http://www.linksys.com/products/product.asp?grid=34&scid=29&prid=639) which looks very good and has their new design since being bought by Cisco. The nice thing about this product is that it can have two internet connections and either share bandwidth between them or use one as a backup only.

Whatever router you go for I suggest you go to http://www.broadbandreports.com/forums/all and search for things like 'BEFVP41 vpn problem' to get an idea if people are having any problems with it. For example there are a couple of people having problems with the RV042 and Bell South DSL.
