I have a quick question here. I'm looking for a router to use for one of my business clients that will provide complete blocking and filtering capabilities for anything except web, email, and possibly instant message. Everything else especially and including all types of file sharing needs to be prohibited.
This is for a business retail location that offers free wifi to their customers. Recently they were hit with a copy right infringement notice from their ISP. They have a basic Netgear router that only has port forwarding available and after a bit of investigation it appears someone secretly living nearby or in the public nearby is leeching off their wifi getting movies, music, porn, etc.
For now the wifi has been temporarily shut off, but the owner wants free wifi back for customers. However he wants it so that the web is open, ability for guests to use email apps on their phones (smtp, etc) is open, but that is about it. He explicitly wants everything else to be blocked.
What router would do this? Hes willing to pay the cost of a router that offers these features. I looked into DD-WRT which can do this... with IPTables. I'd like to have something a lot less complicated and built natively into a routers firmware directly.
