Hello Cisco World.
Looking for some assistance asap on this one. Been going through the Support Community and can't find the exact details I need to get my NATs to work.
Here's the scenario:
Several WAN sites connecting to a MPLS network. I need to be able to send a public address block inside across the WAN to a remote router. From there it needs to source NAT to the interface of that remote router.
MAIN Router - FA0/0 192.168.100.1 /24 Serial T1 (ATT) 18.104.22.168 /30
Remote Site Serial T1 (ATT) 22.214.171.124 FA0/0 172.31.31.56 /24
IP Route (Public IP Block - 126.96.36.199 /24 172.31.31.1 --> Behind the Remote FA0/0 .56 interface
So that part work. I did before and after trace routes, and traffic no longer goes across the internet but across the private WAN.
The data center host says to "All traffic from Customer to the public network (188.8.131.52/24) should be routed over the new MPLS link. Customers MPLS end point device should source NAT all traffic to Datacenter as 172.31.31.56. The end point device should route inbound traffic (to Datacenter) to 172.31.31.1."
So based on that I followed the link here :
I know it's pretty simple. Just can't figure it out.
ip route 184.108.40.206 255.255.255.0 172.31.31.1
ip nat inside source static 172.31.31.56 192.168.100.250

Any help would be appreciated. Thanks, Brandon
