firewall dos-protect dns-replay-attack
A DNS replay attack occurs when an individual intercepts traffic, analyzes the captured packets
and obtains authentication information. They can then use this information to gain access to
other systems by reinserting the authenticated packets on the Internet and replaying them.
To disable the DNS replay attack check, use the no form of the command. By default it is
disabled.
When this command is enabled, the DNS connection limit is 2,000.
