NAT a local ip address to reach a remote ip address
I'm trying to setup access to a remote host from my network using an internal address.
Host 1 - 172.31.19.11
Router 1 (Can't access this router)
Router 2 - Full Control (Cisco 2800)
Host 2 - 10.52.120.100
Basically I want to be able to ping **10.52.120.73 and reach 172.31.19.11
Currently I can ping 172.31.19.11 from the 10.52.120.0 network, but I have a project I'm working on that will require I be able to connect to that remote host on a local ip address. (inter-connecting hosts on separate MPLS networks)
I tried using an outside nat on the serial interface of Router 2: ip nat outside source static 172.31.19.11 10.52.120.73
I can ping 10.52.120.73 from 10.52.120.96 but when I try to telnet to this address it fails. It also fails when I try to telnet to or ping 172.31.19.11 so I'm guessing that the outside nat is also changing the address of the 172.31.19.11 coming into my network.
Here's my nat translation
Pro Inside global Inside local Outside local Outside global
I've configured nat quite a bit for an outside address pointing to an internal device but this is the first time I've tried to point an internal address to an address on a separate network. Any help would be appreciated.
