Looking for a online port scanner

[LightingBird]

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 everyone that responded. But had to delete your posts.

Due to the Security Risk involved with such a question we can not give advice.

Since it could be used against members of this site as well. Advise your people to use Google or Live Search for Shields Up. It will be run locally on their PC and from there you can advise them how to continue.

Other than that we can not offer any other advise due to the security risks involved to our members.
