It has been a long time since I have needed a new firewall, and I would like some pointers on developing a short list for the following requirements:
- Firewall should not only support rule-based processing on the usual variables (IP, UDP/TCP, Source and Target Port) but also be capable of inspecting the protocol traffic over the port. This would be to prevent someone from running a different protocol over an open firewall port.
- Support a minimum of 30 IPs on the inside part of the firewall.
- Extremely easy user interface, preferably using a native Windows application
- Cost under K
If there is a good article reviewing these types of firewalls please supply the URL.
