ASA5505 - No Internet Access after upgrade to 9.2version

Flo AM · ‎08-07-2014

Dear all,

I post here a discussion because after many hours to troubleshoot on this issue, I have still no found how to do it so solve my issue.

Few days ago, I upgrade my CISCO 5505 to 9.2 version and 7.2 asdm version. Since, this upgrade, my VPN tunnel is UP and my users can connect to applications on my site and open Intranet site but they have not Internet connection/access since this upgrade...

I think issue is related to NAT issue but I cannot found how to do it.

Below, my running config :

Hi Florian,

Also you need to place your real ip address in interface ACL's instead of NATed ip address...

Regards

Karthik

nkarthikeyan · ‎08-07-2014

Hi,

I do not see any NAT configured for your device.... I hope you have upgraded from the older ASA OS version to the newer version. Could you please give the NAT statements which was configured on your old version?

for eg: If you have a PAT configured pointing your outside interface... then

nat (inside, outside) source any dynamic interface

for no-nat

object network ZAG_L2L
subnet 10.90.0.0 255.255.255.0

!
object network Trafic_vpn_MainSite_L2L1
subnet 10.239.80.0 255.255.248.0

!

object network Trafic_vpn_MainSite_L2L2
subnet 10.239.88.0 255.255.248.0

!

nat (inside,outside) source static ZAG_L2L ZAG_L2L destination static Trafic_vpn_MainSite_L2L1 Trafic_vpn_MainSite_L2L1

!

nat (inside,outside) source static ZAG_L2L ZAG_L2L destination static Trafic_vpn_MainSite_L2L2 Trafic_vpn_MainSite_L2L2

Hi nkarthikeyan ,

You're right, in the behind configuration, there aren't any NAT configured for the simple reason which's Firewall is on production on another site and users must to connect to our Intranet to working properly so until I found a solution, I do some tests only with one desktop located on site...

I tried to add this command on my configuration but when I do it, I lost connection with computer of my site of ZAG ...

ASA5505-ZAG(config)# nat (inside,outside) source dynamic any interface

Also, I tried this configuration but without success also :/

for no-nat

object network ZAG_L2L
subnet 10.90.0.0 255.255.255.0

!
object network Trafic_vpn_MainSite_L2L1
subnet 10.239.80.0 255.255.248.0

!

object network Trafic_vpn_MainSite_L2L2
subnet 10.239.88.0 255.255.248.0

!

nat (inside,outside) source static ZAG_L2L ZAG_L2L destination static Trafic_vpn_MainSite_L2L1 Trafic_vpn_MainSite_L2L1

!

nat (inside,outside) source static ZAG_L2L ZAG_L2L destination static Trafic_vpn_MainSite_L2L2 Trafic_vpn_MainSite_L2L2

!

And to finish my questions, can you explain me this point please :

Also you need to place your real ip address in interface ACL's instead of NATed ip address...

Thanks for your support !

I really appreciate it !

nkarthikeyan · ‎08-07-2014

Hi,

Can you try like this for internet access.

no nat (inside, outside) source any dynamic interface

object network ZAG_internet
subnet 10.90.0.0 255.255.255.0

nat (inside,outside) dynamic interface

access-list inside_access_out extended permit ip10.90.0.2 255.255.255.0 any

!

access-group inside_access_out in interface inside

!

You can retain the No-nat ACL, which is correct.....

And to finish my questions, can you explain me this point please :

Also you need to place your real ip address in interface ACL's instead of NATed ip address...

In earlier pre-8.3 versions of ASA versions, you will always mentioned the NATed ip address in the access-list..... in post 8.3+ version you need to mention the real ip address in the access-list....

say you have a web server inside your network, which has the real ip of 10.0.0.1 and NAT IP as 1.1.1.1, in old OS versions you will be pointing 1.1.1.1 in outside interface ACL to filter the traffic... but in newer versions you need to have 10.0.0.1 mentioned in order to get that work.

Hi again,

I had your recommendation into my configuration but unfortunately doesn't work yet ...
When I add this config, I lost access to my Intranet portal which is after VPN tunnel... (ip of portal intranet is 10.239.83.2) and I have not Internet access..

It's really strange because I can ping google.com from Firewall and I have access on desktop wih Teamviewer application even if I have not access to Internet on it

nkarthikeyan · ‎08-07-2014

Hi,

can you share me your configs to my personal id nkartheekeyan@outlook.com?

Please make sure that you hash out the sensitive information.

Karthik

Hi,

I've just sent you the running config of my firewall ASA 5505.

Thank you very much for your help here.

Best Regards,

Florian
