You have a host that is assigned an IP from private address space that needs to access public addresses on the internet. AT the same time, a system from the public network needs to access the services of that system. You have plenty of public addresses available for use. Which type of NAT would you use?
A.
VIP
B.
MIP
C.
NAT-dst
D.
NAT-src
Explanation:
Mapped IP (MIP) is a direct one-to-one mapping of one IP address to another. The NetScreen device forwards incoming traffic destined for a MIP to the host with the address to which the MIP points. Essentially, a MIP is static destination address translation, mapping the destination IP address in an IP packet header to another static IP address. When a MIP host initiates outbound traffic, the NetScreen device translates the source IP address of the host to that of the MIP address. If you have plenty of public addresses available then you should use a MIP.
If you have one public address available then you should use a VIP.
