Hi All,
I have a software VPN client that connects just fine to the PIX 501 VPN, but I cannot ping or telnet to any services on the LAN. Below is my config and results of show cry ipsec sa. I would appreciate any suggestions to fix this.
It's been a while since I have done this. When I check the DHCP address received from the VPN, the default gateway is missing. IIRC, that is normal. What is strange is that when I ping, Windows does not show any sent packets.
Thanks,

Hi Deryck,
Your NAT-Exemption is missing. Issue the following commands on the pix:
access-list nat-exempt permit ip any 10.0.1.0 255.255.255.0
nat (inside) 0 access-list nat-exempt
You can also replace any keyword with your specific internal networks, if you want.
This should fix it.

Hi Shikhar,
Thanks for the response. I added the two lines, but I still cannot ping on the local network.
When I run an ipconfig in Windows after connecting to the VPN, this is what I get:
Ethernet adapter Local Area Connection 3:
Connection-specific DNS Suffix: xxxx.biz
IP Address: 10.0.1.205
Subnet Mask: 255.0.0.0
Default Gateway:
Should I see a default gateway listed here? Is there something I need to do to make the Pix respond on a 10.0.1.x address?
Thanks,
Deryck

The one thing that I keep seeing is that there are 0 packets being sent from my Windows XP machine when connected to the VPN. Here is a result of route PRINT from Windows while connected to the VPN:

Hi Deryck,
Sorry for responding late... was in office actually...hmmm..the issue over here is that i find it hard to beleive that your machine is not encrypting the packets. The reason why is say that is because in the output of " show crypto ipsec sa " we do see decrypted packets but not encrypted packets. The only way that we could see the decrytped packets over here is because PIX is actually receving the packets from your VPN client.
Can you please open up your vpn client, go to statistics and send me a screenshot of statistics and route details ?

Hi Shikhar,
It looks like you may be right about the packets not being encrypted. It looks like it's coming from the Pix???
Below are the screenshots.
Thanks,
Deryck

Apply captures on the inside interface of the pix to see if you are receiving any replies from the internal network or not. Here are the commands that you need to apply:
access-list capture permit ip host (ip address assigned to vpn client from pool) host (ip address on your internal network which you are pinging from vpn client)
access-list capture permit ip host (ip address on your internal network which you are pinging from vpn client) host (ip address assigned to vpn client from pool)
capture capin access-list capture interface inside
Now to check the captures issue the command:
show capture capin
Please run around 10 pings to the internal ip address and send me the output.
Also issue the command:
management inside
After issuing this command try to ping the inside interface of your pix and see if you can do that from the vpn client.
09-03-2012 09:29 PM
Ok. I ran the command and I got:
0 packet captured
0 packet shown
For the record, I am testing with a Windows 7 client and a Windows XP client at the same location. On Tuesday, I will give this to another person to test from another location in case my firewall is blocking something here.
Thanks,
Deryck

Hi Deryck,
This is the main problem here. The packets which are coming from the VPN client are getting decrypted on the PIX but never leave the inside interface. This means that PIX is dropping the packets or sending it to some other tunnel. I found another problem in your config. Can you tell me why do you have this statement:
crypto dynamic-map outside_dyn_map 20 match address outside_cryptomap_dyn_20
Please try removing it and then try the connection.

Hi Shikhar,
I just removed that line but there is no difference in the VPN. I checked the statistics and pinging hosts on the LAN, but no change.
Thanks,
Deryck
09-04-2012 02:09 PM
Hi Deryck,
Do you have a support contract with cisco ? If yes i would recommend opening a TAC case...we can then actually check why exactly packets are not coming on the inside interface.
Also try reloading your pix to see if it makes any difference
