NAT and hide NAT on a router

[campbech1]

I've been trying for a while to get a router working between two sites and am requesting some assistance.

Router on my end has three interfaces connected:

Gi0/0.100 - internal to my network - 10.138.247.235/29

Gi0/0.200 - internal to my network - 10.138.247.243/29 (admin down currently)

Gi0/1 - connected to another hospital's firewall - 10.10.246.6

Firewall interface on the remote hospital's side is 10.10.246.1

I can setup a policy nat for all of my networks to talk to the other hospital without any issues, but we have a server network that we want to keep the original IP addresses.

When I remove the 10.200.128.x server network from the NAT ACL, that network is no longer able to communicate with the other hospital.

If I'm not NATing that 10.200.128.x server network, wouldn't/shouldn't it stay original when it leaves the Gi0/1 interface?

Check the other end has a route to this host/server point to your router

The traffic might go from the server but other devices dose not where to send the traffic back

Simple static route on other routers could fix it if they don't have route to it

Hope this help
