VPN Access HELP

woodjl1650
Level 1
Level 1

I have setup VPN access to my ASA 5505...I am finally able to connect and recieve and IP address from it.  But now I stumped on why I can not access my network.  My network is as follows:  Cable Modem --->ASA 5505--->Cisco 3660 Router--->Cisco 2900XL Switch--->Windows 2008 Server--->Client PCs.  Can anyone help me figure out where I am going wrong?

SInce you already have a default route to the ASA, you don't need the more specific one.

But, looking at the most recent ASA config you posted, I think there was some confusion about the split tunnel config.

You have

access-list VPNWoodHome_splitTunnelAcl standard permit 192.168.2.0 255.255.255.0 
access-list WoodVPN_splitTunnelAcl standard permit 192.168.2.0 255.255.255.0 
access-list Split_Tunnel_List standard permit 192.168.1.0 255.255.255.0 

But only one of these is actually used in the group-policy.

group-policy WoodVPN attributes
  split-tunnel-network-list value WoodVPN_splitTunnelAcl
So my suggestion is to add:

access-list WoodVPN_splitTunnelAcl standard permit 192.168.1.0 255.255.255.0
(and remove the other 2 access-lists unless they're used for something else)

One other thing to add....when I connect to the ASA via VPN, I loose my internet connection.  I believe it could be something to do with the DNS.

this route is bad

route inside 192.168.3.0 255.255.255.0 192.168.2.2 1

also you need to exempt the traffic from internal network to vpn pool from natting

i see you have this

access-list inside_nat0_outbound extended permit ip 192.168.2.0 255.255.255.0 192.168.3.0 255.255.255.240

nat (inside) 0 access-list inside_nat0_outbound

i am just wondering if you dont need 192.168.1.0 to be accesible to your vpn clients

this says your vpn clients are accessible using inside, pl remove that when you connect vpn client it will automatically install a route pointing to outside

regarding losing internet connectivyt it is bcoz you need to implemtn split tunneling

access-list split standard permit ip 192.168.2.0 255.255.255.0 (basically your internal network)

group-policy VPNHome attributes

 split-tunnel-policy tunnelspecified
 split-tunnel-network-list value Split_Tunnel_List

please find this link useful

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080702999.shtml

hope this helps, if so please mark this query answered

Alright, I am able to access the Internet now while logged into my VPN, but still unable to access my network.  I don't fully understand what you mean by this:

access-list inside_nat0_outbound extended permit ip 192.168.2.0 255.255.255.0 192.168.3.0 255.255.255.240

nat (inside) 0 access-list inside_nat0_outbound

i am just wondering if you dont need 192.168.1.0 to be accesible to your vpn clients

this  says your vpn clients are accessible using inside, pl remove that when  you connect vpn client it will automatically install a route pointing to  outside

This is the first VPN I have tried to setup, so I am not too experienced with this.  Can you please take a look at the config and see if you can spot where I am going wrong?

Thanks so so much.

Hi Jonathan,

What is the subnet that you are trying to access over the VPN from the PC running VPN Client ? If you are trying to access 192.168.1.0/24 please add the following lines to the config

access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.240

access-list Split_Tunnel_List standard permit ip 192.168.1.0 255.255.255.0  ( This is the same ACL that you are using in the group-policy to define split-tunneling as follows : )

group-policy VPNHome attributes

 split-tunnel-policy tunnelspecified
 split-tunnel-network-list value Split_Tunnel_List

I hope this helps. Also what OS and version of the VPN Client are you running ? 

Cheers,

Namit

Ok added that line, still not network access.  I am using Cisco VPN Client 5.0.  With the group policy attributes, was that something I needed to input?  My subnet is all 255.255.255.0 I am not using any other subnet than that one.

Thanks.

hi jonathan,

as i mentioned in my previous post please remove this line, which is wrong and this will give you access to your network

route inside 192.168.3.0 255.255.255.0 192.168.2.2 1

you can remove it by prefixing no beofre this and entering the comamnd


-----------------------------------------------------------------

what i meant when i asked you about 192.168.1.0 network is as follows

since asa is a device which needs natting when we move from sec zone to another, when we go from inside to vpn (which is in outside) we need natting

now by the rules you have you are natting traffic from internal to outside (internet), but if you nat this will not go through vpn so you will have to no nat and this is done by inclusing this vpn traffic in nat 0 acl

hope this helps

please mark (rate ) this, if it helps

I removed that line and I believe the natting is correct too....below is the currnet running config, still no network access.  Does the Cisco 3660 router have anything to do with it?

what r you trying to access or ping???

issue the command

management-access inside

after this ping 192.168.2.1 from the client

you shold be able to ping

all you need on 3800 router is a route to get to vpn client which i assume is correct

also i dont quite understand why you have

 network 192.168.3.0

in your rip config


could you please clarify if 192.168.3.0 is only for vpn clients or your other internal networks as well

also lastly when you connect go the firewall and issue the command

show crypto ipsec sa peer

Well if I understand VPN corretly I should be able to access my other computer on that network as well as my network drives once I am connected through a VPN, correct?  I am able to ping and reply to 192.168.2.1, but not able to see any of the other PCs on my network.  192.168.3.0 is only for VPN clients via the ASA, all other DHCP happens on the 3660.

hi jonathan,

i understand your intention, i just wanted to clarify

now that you can ping inside ip that means vpn is fine

what internal ip are you trying to ping from your VPN client

192.168.1.0 255.255.255.0  this is the internal network where everything is connected.

i am pretty sure it is the routes on the router behind the firewall, my guess is you are able to ping everything on 192.168.2.0 network

try this

crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set reverse-route 

after this disconnect and connect again

if still doesnt work paste the output of

show crypto ipsec sa

Do that on the ASA or Router?

on ASA

my last post must have confused u bcoz of multiple things in my head

please try it on asa
