etsysNatIpv4ConfigInspectDNS
Module: ENTERASYS-NAT-MIB
OID (symbolic): ENTERASYS-NAT-MIB::etsysNatIpv4ConfigInspectDNS
OID (numeric): 1.3.6.1.4.1.5624.1.2.75.1.2.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object contains the state of NAT IPv4 Inspect/Fix up DNS. NAT DNS packet inspection and fix up consists of parsing DNS request or response packets, identifying IP addresses contained within that may need to be NAT'ed, and fixing up the DNS packet with the appropriate NAT translations. - `disabled', NAT does not inspect DNS packets that are being forwarded by the NAT process. - `enabled', NAT inspects DNS packets that are being forwarded by the NAT process.
What is etsysNatIpv4ConfigInspectDNS?
This turns on or off DNS packet inspection/fix-up for NAT, where the device rewrites IP addresses embedded inside DNS request and response payloads as they pass through. Enable it when internal DNS servers return addresses that need to match the NAT-translated view seen by clients on the other side; it's disabled by default.
