IOS NAT :- getting from inside to public IP

Hi,

I am using IOS 12.4 on a 2811.

I have NAT setup as :-

Fa0/0 set as inside

Dialer0 set as outside

Now I also have some static NAT entries for some servers.

But when I try and access one of the staticly NAT'ed servers from inside, using the Public IP address, it fails.

I can ping the server from inside using the public IP address, but cant make any TCP connections.

I tried passing traffic through a loopback interface by seting a policy on Fa0/0 to send packets ment to the Public addresses via the loopback, but no traffic seems to go through.

Have also tries route_maps on the nat, but to no avail.

Is this even possible ??

i,e Open a TCP connection from 10.1.1.x to 212.x.x.103, where 212.x.x.103 is staticly NAT'ed and 10.1.1.x gets PAT'ed to 212.x.x.101 ??

can you post config, the problem may be on your acl and where you apply acl under.
