As a mechanism of enforcing access control between network and system, firewall is an important means to ensure network security. Different firewall systems can be tailored to different requirements and application environments. Firewalls can be large to consist of several routers and bastion hosts, or small to just the packet filtering functionality provided by a firew
and disadvantages. although most applications can be supported by NAT, there are also exceptions, such as video streams and VPN. A bridge firewall can solve these problems. The firewall can be deployed between the ADSL router and the internal network to protect the network, but the configuration does not need to be modified at the same time. The last obstacle is that iptables is completely bypassed in the
