Name Resolution

The Device > Log > Name Resolution page includes settings for configuring the name servers used to resolve IP addresses and server names in the log reports.

The SonicWall network security appliance uses a DNS server or NetBIOS to resolve all IP addresses in log reports into server names. It stores the names/address pairs in a cache, to assist with future lookups. You can clear the cache by clicking Reset Name Cache button.

Selecting Name Resolution Settings

The firewall appliance can use DNS, NetBIOS, or both to resolve IP addresses and server names.

In the Name Resolution Method list, select:

• None: The security appliance does not attempt to resolve IP addresses and Names in the log reports.
• DNS: The security appliance uses the DNS server you specify to resolve addresses and names.
• NetBIOS: The security appliance uses NetBIOS to resolve addresses and names. If you select NetBIOS, no further configuration is necessary.
• DNS then NetBIOS: The security appliance first uses the DNS server you specify to resolve addresses and names. If it cannot resolve the name, it tries again with NetBIOS.

Specifying the DNS Server

You can choose to specify DNS servers, or to use the same servers as the WAN zone.

1. Select Specify DNS Servers Manually or Inherit DNS Settings Dynamically from WAN Zone. The second choice is selected by default.
2. If you selected to specify a DNS server, enter the IP address for at least one DNS server on your network. You can enter up to three servers.
3. Click Accept.
