NAT Pool Addresses

Before TNSR can perform any type of NAT, an inside and outside interface must be set and the outside/external addresses (e.g. WAN-side) must be listed in a NAT pool. These pools are added from configure mode (Configuration Mode) in the TNSR CLI (Entering the TNSR CLI).

For a single external address, define a NAT pool like so:

tnsr(config)# nat pool addresses 203.0.113.2

For multiple addresses, use a range:

tnsr(config)# nat pool addresses 203.0.113.2 - 203.0.113.5

TNSR also supports using an interface to automatically determine the pool addresses:

tnsr(config)# nat pool interface GigabitEthernet0/14/1

For Outbound NAT this is typically the interface set as ip nat outside.
