Cisco remote VPN NAT issue

[jibsoni]

Dear all,

I am facing an issue , which needs your valuable support.

As per the  attached diagram , remote users are getting ip address 192.168.2.x , internal IP = 192.168.1.x , DMZ ip = 172.16.1.x and 10.0.0.x network is accessed via router connected on DMZ in which i dont have control.

My issue is that remote users want to access 10.0.0.x network but they can't , at the same time they can access DMZ and internal network.

I have tried no NAT as below and i removed first line of ACL as well, but the result is same

access-list 160 permit ip 10.0.0.0 255.0.0.0 192.168.2.0 255.255.255.0

access-list 160 permit ip 172.16.1.0 255.255.255.0 192.168.2.0 255.255.255.0

nat (dmz) 0 access-list 160

i wish to try NATing 192.168.2.x  traffic using a DMZ IP addess when packets are destined to 10.0.0.x.

can some one suggest me on how to proceed ?

Hi,

You need to look at a dynamic policy NAT and nating the VPN users to either the DMZ interface or an address within DMZ range which is dedicated to that purpose.

Hello,

You could do a :

NAT (outside) 1 192.168.2.0 netmask 255.255.255.0 outside

global (dmz) 1 172.16.1.x

Can you do a packet-tracer and show us the result of that, this will lead us to a nat or something else issue.

The No_Nat configuration is perfect.

Hello,

Here is what I want you to do now:

access-list test permit ip 192.168.2.0 255.255.255.0 10.0.0.0 255.255.255.0

nat (outside) 10 access-list test outside

global (dmz) 10 interface

Regards,

Let me know the result.
