I am having doubt about nat0. Following is my nat controller list
global (outside) 10 interface
global (dmz-MHR) 10 interface
global (dmz-vendor) 10 interface
global (dmz-vendor) 5 MHR-redhat-PUB
nat (inside) 0 access-list inside_nat0_acl
nat (inside) 5 access-list redhat_nat
nat (inside) 10 0.0.0.0 0.0.0.0
nat (dmz-MHR) 0 access-list NoNatAll
nat (dmz-remote) 0 access-list NoNatAll
nat (dmz-vpn-internal) 0 access-list dmz-vpn-internal_nat0_outbound
nat (vendor2-Network) 0 access-list NoNatAll
nat0 is working well for defined list. But I am having doubt whether I need to create nat0 in the outside interface so that specific traffic coming from outside to inside or from inside to outside will be natted.
Please clarify this basic doubt.
