Administering an ISP Installation

Bottlenecks

Sometimes the firewall can turn into a bottleneck if there is a lot of Internet traffic, because it must check every single packet of information flowing in and out of the cluster. To alleviate this problem, see if your firewall software allows you to set up multiple firewalls. If so, you can add other firewalls between the access router and the router connected to the switch, in order to meet the new bandwidth requirements. This way, traffic can be divided among multiple firewalls.
