Yesterday, I went to the customer where to configure a Symantec Gateway Secutiry 5420 firewall, some experience, there is a big problem, killing ^ 0 ^
Configuration steps:
Step 1: Planning the network
Customer network situation, through the Internet, then directly access to the router, the router is connected to the firewall, and then access the internal network master switch.
Step 2: Set the network card address to connect to the firewall management interface
The internal network IP192.168.0.5 and its corresponding subnet are set through the firewall front panel. Note that this firewall sets an IP address through the front panel function, that is, set the intranet, or set the external network, set the Gateway when setting the external network. At the same time, you should write down your password (the login management interface needs).
Any internal machine can access the firewall, enter https://192.168.0.5:5:2456/ of the browser address bar, you can enter the management interface of the firewall, and you need to get authentication. At the same time, this management interface is based on Java-developed operational environments where Java is installed. If there is no installation on the client, the display will be installed after logging in. Log in to the default management user admin, the password is the password in step I.
Step 3: Add rules
Add service group DNS to allow the external network DNS address set on the client to pass through the firewall.
Add Rule, add a new rule, free access to the external network and intranet.
This allows the client to be online, but in this case, the firewall has a small role.
Next step, it is exhausted to write ^ 0 ^
