Don't you think the background section should be deleted? It's very redundant to the Network firewall page. Also, the language could use some cleanup (such as replacing "fire wall" with "firewall". — Preceding unsigned comment added by Anders K Berggren (talk • contribs) 10:12, 7 September 2012 (UTC)[reply]

There are not only bridged-mode and hypervisor-mode, that's more VM-mode and hypervisor-mode. Because a VM based firewall can be bridged-mode (transparent / L2) or routed-mode (inter-subnet / L3 gateway). Also the article is no talking about NIC-level firewalls, maybe FastPath and SlowPath and an important part about Service insertion is missing. — Preceding unsigned comment added by 194.250.5.173 (talk) 16:31, 1 March 2018 (UTC)[reply]
