After about ~1 year of having the Cisco VPN Client connecting to a ASA 5505 without any problems, suddenly one day it stops working. The client is able to get a connection to the ASA and browse the local network for only about 30 seconds after connection. After that, no access is available to the network behind the ASA. I tried everything that I can think of to try and troubleshoot the problem, but at this point I am just banging my head against a wall. Does anyone know what could cause this?
Here is the running cfg of the ASA

try putting you deny ACL (access-list AnyConnect_Client_Local_Print extended deny ip any any) at the end of the ACL list.

Hi Matthew,
You use a VPN pool from the same subnet of the inside subnet (192.168.2.70 -192.168.2.80). This could lead to some unexpected behaviours. So i suggest that you use a unique pool and rely on routing to achieve communication between the inside subnet and the pool .
One question here, when the problem happens (after 30 seconds), is the tunnel kept up or you see the VPN client disconnected ?
The following troubleshooting will clarify the situation more :
- set the following captures:
capture capin interface inside match ip host < IP Assigned to the VPN client> host
if you cannot know the IP assigned to the client, use 192.168.2.0 255.255.255.0
- connect from your VPN client
- initiate a continous ping to the internal IP (set in the capture)
- get the output of "show cap capin" from the ASA
- get the outputs from the ASA :
show crypto isakmp sa
show crypto ipsec sa
when the problem starts:
- "clear cap capin"
- wait for seconds, and get the capture again: show cap capin
- get the ASP drop captures
cap asp type asp-drop all
show cap asp
Hope this helps

After the problem happens, the tunnel is kept up (the VPN client does not disconnect). All that changes is that the local network can no longer be accessed.
Attached is the capture you requested. From the VPN client to the server they access. I ran a continuous ping until it stopped responding, then stopped the captured and saved it. Let me know if that is what you needed.
Thanks so much for the replies!

Matthew,
The captures you attached show normal traffic exchange for some period of time. However, the captures alone cannot point to the problem.
let's do the following when the problem is happening:
- connect from your VPN client
- initiate a continous ping to the internal IP.
Wait until the problem starts:
- run: "clear crypto ipsec sa counters"
- wait for some seconds then get the following outputs from the ASA :
show crypto isakmp sa
show crypto ipsec sa
- set the captures:
capture capin interface inside match ip host < IP Assigned to the VPN client> host
- get the ASP drop captures as following:
cap asp type asp-drop all
show cap asp
Is it possible that you use a VPN pool different from the inside network range ?
Regards.

Thanks for your quick reply!
I did exactly as you requested, and the results are attached.
As far as using a different set of IP addresses for the VPN pool, I have no problems with that at all, but would not know what to do to set up the routing so that the pool can access the internal network (I am not that familiar with Cisco CLI).
Thanks,
Matthew

Hi Matthew,
The SAs output shows that when the problem is happening, decaps are incresaing but no encaps, which indicates that the problem is in returning traffic from the internal hosts to the VPN pool. I didn't see any packets in the inside captures (capin), so based on that i assume that the arp consistency fails at some time from the internal hosts to the ASA.
I suggest that you get rid of this troublesome setup by using a distinct VPN pool. This change should be straighforward:
For example:
asa(config)# ip local pool NEW_POOL 192.168.3.1-192.168.3.254 255.255.255.0
tunnel-group NCHCO general-attributes
address-pool NEW_POOL
You don't need to change routing in the internal subnet as long as it uses the ASA as a default gateway, otherwise you will need to add a specific route toward the new pool with the ASA as next-hop.
If you want to continue troublehsooting the current setup, you need to focus on captures at the inside host, ARP entries at the inside hosts, ARP debugs at the ASA, and captures at the ASA.
Hope this helps

I made the change that you requested by moving the VPN pool to the 192.168.3.0 network. Unfortunately, now traffic isn't flowing to the inside network at all. I was going to make a specific route as you suggested, but as far as I can see the routes are already being created correctly on the VPN client's end.
Here is the route print off of the computer behind the (test) client:

You need to add nat-exempt rule for the new VPN pool:
object network obj-192.168.3.0
subnet 192.168.3.0 255.255.255.0
nat (inside,outside) source static NCHCO NCHCO destination static obj-192.168.3.0 obj-192.168.3.0
let me know how it goes with you.

I did as you suggested above, but the traffic is still not getting to the 192.168.2.0 network. In trying to diagnose, I saw that the traffic was bypassing the tunnel in the VPN client (the packet count under Tunnel Details in VPN Client statistics show packets as bypassing). The VPN is set up as split tunneling, so I tried adding the 192.168.3.0 network to the ACL that specifies networks to tunnel but it did not make a difference. Any idea what would cause that?
Thanks once again,
Matt
10-14-2013 11:20 PM
If you go to Status -> Statistics -> Route Details in the VPN client, do you see the 192.168.3.0/24 network ?
Is the new behaviour happening with all clients ?

No, under route details it only lists the 192.168.2.0/24 network. And yes, the new behavior is happening with all clients.
Matt
10-15-2013 07:12 AM
Yes i meant 192.168.2.0/24 ( the inside subnet). That should be enough.
So you don't see the " Encrypted" counter increasing at all ?
If so, please attach the output of "ipconfig /all" from an affected PC. I will need to make a lab reproduction to investigate the details.

Unfortunately, no, the encyrpted packet count is not increasing, all of the traffic is bypassed.
Here is the ipconfig /all from the machine I am using to test:
