I'm trying to get IPSec VPN working onto a new Cisco ASA5505. Pretty standard configuration.
Setup:
* Cisco VPN client on Windows 7 (v5.0.07.0290 x64 on Laptop1 and v5.0.07.0440 x64 on Laptop2)
* PPPoE/NAT and internal DHCP on the ASA were configured with the Startup Wizard in ASDM
NATting is working fine - internal PCs get an IP address in the 192.168.2.0/24 range and can all access the Internet.
I wanted to be able to connect from anywhere to the ASA in order to reach one of the internal servers. Should be pretty basic.
First I tried with the built-in ASDM IPSec Wizard, instructions found here.
VPN clients can connect to the ASA, are connected (until they're manually disconnected), but cannot reach the internal network nor the Internet. Note VPN client can connect fine to a different VPN site (not administered by myself).
Client logs show following error messages:
1 15:53:09.363 02/11/12 Sev=Warning/3 IKE/0xA300005F

I've already tried the suggestions from this link, although the problem is different there (as the user can still access the internet, even without split tunneling, which I cannot).
A show run shows the following output (note in the below I have tried a different VPN network: 192.168.3.0/24 instead of 172.16.1.0/24 seen in the Client log)
Result of the command: "sh run"

Unfortunately I'm getting the same "AddRoute failed to add a route with metric of 0: code 160" error message.
I'm very confused as this should be a pretty standard setup. I tried to follow the instructions on the Cisco site to the letter...
The only "differences" in my setup are an internal network of 192.168.2.0 (with ASA IP address 192.168.2.254) and PPPoE with DHCP instead of no PPPoE at all.
Does anyone know what's going on?
02-23-2012 12:15 PM
Anyone?
I've started from scratch again and am facing the same issue. Very frustrating :/
02-23-2012 12:34 PM
Please copy your current config on forum and tell me please what is that you cannot access while being on vpn client.
thanks
02-23-2012 12:39 PM
Have you tried it from another PC?
02-24-2012 02:14 AM
Yes, I have tried from a different laptop - same results. Using that laptop I can connect to a different IPSec site without issues.
Please find my renewed config below:

Please change your ACL as shown below...
access-list inside_nat0_outbound extended permit ip 192.168.2.0 mask 255.255.255.0 192.168.50.0 255.255.255.224
Please confirm that your inside hosts have its default gatway assign.
If your inside switch is a Layer3 switch please make sure that you have a static-route in place to push vpn bound traffic to FW's inside address as shown below.
"ip route 192.168.50.0 255.255.255.0 192.168.2.254"
Please include this line as well on your dynamic crypto config.
crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set reverse-route
To access the internet via VPN client connection to corprate network use the config below.
nat (outside) 1 192.168.50.0 255.255.255.0
Let me know the result
Thanks
