NAT Virtual Interface

Rene,

Regarding NAT VI I noticed a limitation I am having when configuring this and I was wondering if you can shed some light on this.

First off, great explanations and examples of NAT VI. Network Lessons has definitely been one of my go to sources for studying and I have been recommending this site to co-workers which find this site amazing as well.

Back to my question:

When I configure NAT VI I can test my nat translations from within my LAN hitting my WAN ip address ex: (12.1.1.1 port 80) but why can I no longer remote into that device through its local IP ?
From the example given below from 10.1.1.4 I can remote into 10.1.1.2 by hitting 12.1.1.1 port 80 but I cant remote into it locally by 10.1.1.2 80 which does work with domain NAT defining inside and outside interfaces.

ex:
LAN network 10.1.1.0/24
WAN network 12.1.1.0/24

nat translation:

ip nat source list NAT interface FastEthernet0/0 overload
ip nat source static tcp 10.1.1.2 80 12.1.1.1 80 extendable
ip nat source static tcp 10.1.1.4 443 12.1.1.1 443 extendable

Thanks in advance.
