I have a client who has outgrown their office and is now leasing additional office space at a location across the street. This will be my first time setting up any kind of WAN and I am looking for suggestions; specifically suggestion for what type of link to use between the offices. The distance will be less than one quarter mile and some type of directional wireless maybe possible but may be undesirable to the client because of dealing with equipment mounting and landlord issues.
Right now I am leaning heavily toward getting Comcast service to the second location and establishing a VPN to the main office. The new office will only house 5 or 6 desktops; will a Comcast link have enough bandwidth to handle this? Any thoughts on this as well as router suggestions for making the VPN link between the two locations would also be helpful.
I'm also certain, being in the Chicagoland area, that just about every telco product should be available to me as well, although i am not super familiar with their offerings and costs being as most of my clients are small offices (generally fewer than 10 PC's) that typically just have a Cable or DSL link for internet service. Any cost effective telco products can be considered as well.
Also of note, this client has a history of being cheap, so cost will be a big issue in deciding what solution to use. Thanks!
