Basically, I have employees that work from home that use routers. We do not support routers. So I'm looking for a free online website that can basically do a scan to see what ports are blocked. They use programs like outlook(port 80) and an ATT vpn client(port 443). Any ideas?
Sorry to be unhelpful, but it actually sounds like your policy on routers needs to change. Everyone who is vaguely tech-savvy has a router. What is the bigger problem? What don't you support routers for? VPN software?
