The modern stateful firewall is the keystone of network security. Sometimes called a hybrid firewall, it combines the features of other firewall approaches, such as ACLs, application-specific proxies/inspections, and stateful inspection. It also has the features of other devices, such as web (HTTP) cache and specialized servers (SSH, SOCKS, NTP). Most include VPN, and some include IDS.
Strengths:
Maintains most of the speed advantage of a simple stateful firewall.
Application Layer Gateway services provide application security while resolving the NAT issue.
Weaknesses:
Does not provide complete session termination, as would a full proxy.
