I am looking for a site-2-site VPN solution for small business with three sites (~15 users per site), currently on DSL with Netopia ADSL routers and using WAP on internal network. Different internal subnets. Looking for an appliance that does secure VPN in the cost range less than $300 per unit. I am aware there are Linksys & Netgear products in this price range and I am looking for recommendations on a product you may have used and found reliable. Also, for feedback on Cisco 871...Thank You!
