A fun place to discuss colocation services
In addition hardware firewalls may also provide Stateful Packet Inspection (SPI), which also analyzes the content of data packets apart from the source and destination headers. As an Internet capability device, routers assign a unique random IP address to all the PCs within the network so that all the data transfer and web traffic goes via the single IP of the router. This provides added security since attacking individual computers behind a router is much harder than bypassing a simple address translation, which takes data directly to each PC. As such hardware firewalls make better security layers than software firewalls since they are more robust especially if SPI enabled, and make for affordable protection. Under ideal conditions though it is recommended that users install both a hardware firewall as a protection for the network as well as enable software firewalls on individual computers.
