NAT port forwarding with loopback interfaces

Hi,

I think it is a pretty easy question, but i can't find a solution apparently. I have a 877 with loopback interfaces, something like:

interface Loopback2

ip address 111.111.111.111 255.255.255.255

!

interface Vlan2

ip address 222.222.222.222 255.255.255.254

no ip redirects

no ip unreachables

no ip proxy-arp

ip nat outside

ip virtual-reassembly

Loopback1 is the pool of ip assigned from the ISP, the vlan2 interface is the actual point to point to the ISP fiber link

This actually works in outbound direction, and from the external world i am using loopback2 public ip

ip nat inside source list 115 interface Loopback2 overload

But i cant make any portforward inbound to expose some services:

ip nat source static tcp 192.168.1.1 443 interface Loopback2 443

ip nat source static tcp 192.168.1.1 1723 111.111.111.111 1723 extendable

any clues?

thanks
