DNS CACHE PROXY
When you send a DNS query to your browser or to an e-mail address, the DNS server will convert the known domain name (e.g. www.company.com or smtp.company.com) into an IP address and communicate it to you.
The DNS cache proxy allows storing the response and IP address communicated earlier by the server in the firewall’s memory. As such, whenever a similar query is sent, the firewall will respond more quickly on behalf of the server and will provide the saved IP address.
The DNS cache proxy window consists of a single screen, divided into two sections:
- A table listing the DNS clients allowed to use the cache.
- A drop-down menu allowing the definition of advanced properties.
