Cisco 877 - NAT on address pool

[growse]

On my broadband connection, I've got both a /32 and a /29 network allocated to me. The /32 address is set up on the dialer1 interface and nat is configured so that internal clients are dynamically natted out on that address.

What I'm trying to do is to allow some port forwarding to internal clients to occur from some of the address in the /29 network. I can traceroute from the internet to addresses in the /29, and they end up at the /32 address, which is what I'd expect as that's the primary internet-facing address of the router.

What configuration steps would I need to do to tell the 877 to do NAT on the /29 network?

Well if you want to do a 1:1 then you just need a static NAT statement pointing to the internal host if that's what you mean?

ip nat inside source static <internal ip> <global ip>

Is that what you mean? Any communication done by the internal host will get NAT'd to the specified global address

Apologies, I've been a numpty.

I'd set up the nat statements, but had no connectivity. Completely forgot about the access list on the dialer1 interface blocking everything coming in.

Problem solved...
