You need have a dynamic PAT on DMZ interface. But missing NAT-exempt(identity nat) for traffic passing between your DMZ interface and VPN clinets.
Try adding these lines
!
object network VPN_pool
range 172.26.0.10 172.26.0.19
!
nat (DMZ,outside) source static any any destination static VPN_pool VPN_pool
!
01-02-2013 04:29 AM
Hi Enrique,
Thanks for the rating..
your "inside <-> VPN" traffic also needs a identity nat. . You may need to add this line as well.

Hi,
I would consider changing the whole NAT setup a bit
You could start by removing all the following NAT configurations and replacing them with new ones (provided I have understood the situation correctly)
no nat (DMZ,outside) source dynamic any interface
no nat (outside,outside) source static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27 destination static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27 route-lookup
no nat (inside,outside) source static any any destination static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27
no nat (DMZ,outside) source static any any destination static VPN_pool VPN_pool
no nat (inside,outside) source static any any destination static INSIDE_pool INSIDE_pool
It would also seem to me that the following configuration would be useless after configuring what I'm suggesting, so you could remove these also
object network obj_any
nat (inside,outside) dynamic interface
object network DMZ_outside
nat (DMZ,outside) dynamic interface
Leave all other NAT configurations as they are.
The new configurations could be for example
Default PAT for DMZ (First removed rule above)
nat (DMZ,outside) after-auto source dynamic any interface
NAT0 / NAT Exempt style configuration for the VPN Pool for both DMZ and INSIDE networks
object network VPN-POOL
subnet 172.26.0.0 255.255.255.0
object network INSIDE
subnet 192.168.1.0 255.255.255.0
object network DMZ
subnet 10.0.0.0 255.255.255.0
nat (inside,outside) source static INSIDE INSIDE destination static VPN-POOL VPN-POOL
nat (DMZ,outside) source static DMZ DMZ destination static VPN-POOL VPN-POOL
Also one thing that caught my eye was that you have this ACL attached globally yet you have interface ACLs
no access-group global_access global
no access-list global_access extended permit ip any4 any4 inactive
As the only rule in the ACL is set to "inactive" I would suggest removing the "access-group" command for it.
Also please remove this line from the Split Tunnel ACL
no access-list Tunel_Casa_splitTunnelAcl standard permit 172.26.0.0 255.255.255.0
Atleast it seems to me something that should not be there as the ACL defines the networks that need to be accessed through the VPN connection and that network range is the VPN-POOL.
Also consider clearing all NAT translations before testing connections (clear xlate)
If you decide to change the configurations as I suggested, please take a backup of the current configuration so you can change back to the old configuration if needed.

Hi,
Did you mean to say that you can access the DMZ network from the VPN Client but NOT the INSIDE network?
It seems that for the most part your configurations have stayed the same compared to the situation when you made the changes that corrected the situation.
Relating to the NAT configuration it seems you have added this configuration line
nat (inside,outside) source static any any destination static VPN_pool VPN_pool
To my understanding its not needed as we previously configured NAT rules for the LAN to VPN and DMZ to VPN traffic already with the following configurations
nat (inside,outside) source static INSIDE INSIDE destination static VPN-POOL VPN-POOL
nat (DMZ,outside) source static DMZ DMZ destination static VPN-POOL VPN-POOL
You could perhaps try to remove the configuration
nat (inside,outside) source static any any destination static VPN_pool VPN_pool
Or did I missunderstand the problem somehow?

Hello again,
Now I lost the ping with my hosts in the inside interface, is this posible ?

Hi Enrique,
Thanks for the rating..
your "inside <-> VPN" traffic also needs a identity nat. . You may need to add this line as well.
!
nat (inside,outside) source static any any destination static VPN_pool VPN_pool
!
01-02-2013 07:59 AM
Hello,
you tried this I mention, but I still do not have access to the equipment on the inside interface
01-02-2013 08:22 AM
Hi,
I would consider changing the whole NAT setup a bit
You could start by removing all the following NAT configurations and replacing them with new ones (provided I have understood the situation correctly)
no nat (DMZ,outside) source dynamic any interface
no nat (outside,outside) source static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27 destination static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27 route-lookup
no nat (inside,outside) source static any any destination static NETWORK_OBJ_172.26.0.0_27 NETWORK_OBJ_172.26.0.0_27
no nat (DMZ,outside) source static any any destination static VPN_pool VPN_pool
no nat (inside,outside) source static any any destination static INSIDE_pool INSIDE_pool
It would also seem to me that the following configuration would be useless after configuring what I'm suggesting, so you could remove these also
object network obj_any
nat (inside,outside) dynamic interface
object network DMZ_outside
nat (DMZ,outside) dynamic interface
Leave all other NAT configurations as they are.
The new configurations could be for example
Default PAT for DMZ (First removed rule above)
nat (DMZ,outside) after-auto source dynamic any interface
NAT0 / NAT Exempt style configuration for the VPN Pool for both DMZ and INSIDE networks
object network VPN-POOL
subnet 172.26.0.0 255.255.255.0
object network INSIDE
subnet 192.168.1.0 255.255.255.0
object network DMZ
subnet 10.0.0.0 255.255.255.0
nat (inside,outside) source static INSIDE INSIDE destination static VPN-POOL VPN-POOL
nat (DMZ,outside) source static DMZ DMZ destination static VPN-POOL VPN-POOL
Also one thing that caught my eye was that you have this ACL attached globally yet you have interface ACLs
no access-group global_access global
no access-list global_access extended permit ip any4 any4 inactive
As the only rule in the ACL is set to "inactive" I would suggest removing the "access-group" command for it.
Also please remove this line from the Split Tunnel ACL
no access-list Tunel_Casa_splitTunnelAcl standard permit 172.26.0.0 255.255.255.0
Atleast it seems to me something that should not be there as the ACL defines the networks that need to be accessed through the VPN connection and that network range is the VPN-POOL.
Also consider clearing all NAT translations before testing connections (clear xlate)
If you decide to change the configurations as I suggested, please take a backup of the current configuration so you can change back to the old configuration if needed.

Hi !
I believe that with these changes, everything works perfectly now. I have obviously had a big problem with the NAT configuration.
Thank you for everything
02-07-2013 03:53 PM
Hello, I'm having trouble, now when I make a VPN connection, I only see the machines in the DMZ, but I can see the machines that are connected to the inside interface.
Can you help me again please?

Hi,
Did you mean to say that you can access the DMZ network from the VPN Client but NOT the INSIDE network?
It seems that for the most part your configurations have stayed the same compared to the situation when you made the changes that corrected the situation.
Relating to the NAT configuration it seems you have added this configuration line
nat (inside,outside) source static any any destination static VPN_pool VPN_pool
To my understanding its not needed as we previously configured NAT rules for the LAN to VPN and DMZ to VPN traffic already with the following configurations
nat (inside,outside) source static INSIDE INSIDE destination static VPN-POOL VPN-POOL
nat (DMZ,outside) source static DMZ DMZ destination static VPN-POOL VPN-POOL
You could perhaps try to remove the configuration
nat (inside,outside) source static any any destination static VPN_pool VPN_pool
Or did I missunderstand the problem somehow?
