FAQ-Can the Global Address on the NAT Server on an NE20E-S Be an Interface Address

Publication Date:  2019-04-16 Views:  74 Downloads:  0

Issue Description

Can the global address of the NAT server be an interface address?

Device model: NE20E-S


For the devices upgraded to a version later than V800R008C10, the interface IP address must be able to map a port number.


In the view of the NAT instance named cpe1, use TCP on the internal NAT server to reuse the IP address of GigabitEthernet 0/1/1.
