Confused but curious.
int VLAN1
ip address 192.186.1.2 255.255.255.0
ip nat outside
!
int VLAN2
ip address 192.186.2.2 255.255.255.0
ip nat inside
ip route 0.0.0.0 0.0.0.0 192.168.1.1
ip nat inside source list 12 interface VLAN1 overload
....
Does this mean that any system on the VLAN1 interface will be routed without
NAT!

Subject: NAT on outside interface
R1
s0/0 = nat inside
e0/0.100 = nat outside
If traffic is originated with source IP of s0/0, NAT does not occur.
If traffic is originated with source IP of any other interface, including
interfaces that does not have 'nat inside', nat occurs.
Weird question: Is there a way to have the source IP of e0/0.100 converted?
