Hi,
I need help to resolve this issue. I am trying to ping from 172.16.0.196 (coming via "acc-network" interface) address to 10.10.40.20. My packets are getting dropped because of that Global NAT rules.
What should I do to resolve the issue. I need the Global NAT rule to reach 155.10.10.0/24 network via 60.160.160.28 from both "acc-network" and "production" interfaces too.
Here is my config and show details.

Hi,
Add the following:
static(production, acc-network) 10.10.40.20 10.10.40.20
Let me know.

Hi Chamon,
You have to first assign a security level to the "production" interface. Depending on the security level you assign, you can configure the NAT rule.
For the second question, where you want to reach 155.10.10.0/24 network via 60.160.160.28 from acc-network, you have the needed nat in place. Please configure inspect icmp under the global policy map to allow the replies through.
policy-map global_policy
class inspection_default
inspect icmp
Let me know.

Anu

Hi Anu,
It does have correct sec-level. I missed to copy the config file properly.
interface Ethernet0/2
nameif production
security-level 95
ip address 10.10.40.2 255.255.255.0

Hi,
I think I found a technique. I need to keep out off NATing the traffic coming from the "acc-network" interface to "production" interface OR should I use a static NAT for it?
Can someone post me the command to do either of those?
Thanks.

Hi Anu,
It could not fix the problem. Because the both "acc-network" and "production" interface is NATED to "outside" interface of 60.160.160.2 address.
So when the traffic is coming from "acc-network" to "production" it might see as NATED to "outside" interface of 60.160.160.2 address.
We need to source NAT the "acc-network" to some address. The whole "acc-network" interface is behind of 172.16.0.0/24 network.

Hi Chamon,
Can you lower the security-level of the production interface and then apply that static? Or add:
nat (acc-net) 5 0 0
global (production) 5 interface

Anu

Hi Anu,
I made it today.
I lowered the sec-level of acc-network to 90 and put the static route. Many thanks for your continuos support.
static (prodcution,acc-network) 10.10.40.20 10.10.40.20
I do appreciate it.
Thanks.
