i need some help to create the following nat scenario on a cisco 29xx router.
Two companies should hide from each other because they have overlapping networks. There should be a "demarcation" subnet where each company can
route to. (see picture) The router is manged by the us (the customer)
1.) We (customer) should hide all our networks behind the ip address 188.8.131.52
So service provider should see our packets coming from 184.108.40.206
2.) Since we (customer) cannot route to service provider host 220.127.116.11 directly, we want to address target ip 18.104.22.168 to get to service provider host 22.214.171.124, in other words SP host 126.96.36.199 should be visible as 188.8.131.52 for us.
3) Service provider host should be able to address printers (our real address 184.108.40.206), but should address the printer as 220.127.116.11
So we like to have those two demarcation subnets 18.104.22.168/24 and 22.214.171.124/24 to communicate.
Both networks should know only about the demarcation subnets (except our final cpe router that has eth1 in the SP network 126.96.36.199/24)
I tried a lot of setups in my lab, mixing inside/outside definitions, but i must say that i get confused now, and i'm not getting this to work.
Can someone please provide me with a sample code snippet and show me the right direction?
Thanks in advance!
