I am the IT manaer for a medium size company. We have about 45 computers and 3 servers on our network. We have a NAT router firwall currently and it is closed to all ports that are not needed inbound. I have tested this. The firewall/router is maintained and provided by our ISP. I recently have had an issue with a computer connecting to an outside ip address and opening 1000+ ports. Issue explained here http://www.experts-exchange.com/Networking/Q_22036070.html
I would like another hardware firwall that I can controll and limit ourbound ports.
Could someone suggest an easy firewall/internet appliance that is not too $$ and easy to setup and maintain?
