Hi there, please forgive if I have missed any forum protocols as this is my first post.
I am trying to configure Anyconnect SSL VPN. I am able to connect to the VPN on a laptop, witch is able to download the anyconnect client from the ASA. I am unable to ping any of my IP's that are on the inside of my ASA. Before posting here I have spent many hours on forums and watching videos on anyconnect SSL VPN creation and I am following it to the T but still no ping. Any help would be very much appreciated.
Inside 192.168.1.254/24
Outside dhcp
VPN Pool 192.168.250.1-50/24
Inside LAN 192.168.1.0/24

Hi,
Could you add the command management-access inside and then see if you can ping the inside interface of the ASA when connected to the VPN.
If you are able to, then it is most likely the windows firewall blocking the ICMP packets (or whichever firewall is installed on the PC).
If you are not able to ping the inside interface, try changing the NAT rule to be more specific:
no nat (inside,any) source static any any destination static NETWORK_OBJ_192.168.250.0_25 NETWORK_OBJ_192.168.250.0_25
nat (inside,outside) source static inside-network-object inside-network-object destination static NETWORK_OBJ_192.168.250.0_25 NETWORK_OBJ_192.168.250.0_25
nat (inside,outside) source static management-network-object management-network-object destination static NETWORK_OBJ_192.168.250.0_25 NETWORK_OBJ_192.168.250.0_25
Also try running the packet-tracer. It can help in identifying where the drop is. Run it twice in a row, as the first time you run it will most certainly show a drop. The second will show the accurate trace.

I tried the things you suggested, but still no ping over anyconnnect vpn connection. This are the results from the packet-tracer:

doesn't look like your NAT Exempt statement is is being matched.
Could you confirm the IP address that is assigned to the VPN client.
Could you confirm the group policy which is assigned to the VPN client ( this can be easily done using the ASDM Monitoring tab)
Also, your object group and VPN pool do not match up. Though it should not have much to say in this situation it is best to have everything uniform.
object network NETWORK_OBJ_192.168.250.0_25
subnet 192.168.250.0 255.255.255.128
ip local pool vpn_pool 192.168.250.1-192.168.250.100 mask 255.255.255.0
change the local pool to the following:
ip local pool vpn_pool 192.168.250.1-192.168.250.126 mask 255.255.255.128
08-21-2013 05:34 AM
I changed the subnet from object network NETWORK_OBJ_192.168.250.0_25 to 255.255.255.0.
The ip-adres of the anyconnect vpn client is: 192.168.250.1 with gateway 192.168.250.2
The group policy which is assigned: GroupPolicy_anyconnect
08-22-2013 06:46 AM
Could you post a current config please.

It should be enabled by default...but you can try to add the command sysopt connection permit-vpn to ensure that the VPN traffic bypasses interface ACLs.
08-22-2013 07:48 AM
Done that, still not able to ping management interface/inside interface.
08-22-2013 08:05 AM
You will not be able to ping the inside interface unless you add the command management-access inside, as I mentioned in my first post.
08-22-2013 08:29 AM
I have done that command, it's in the config i posted earlier this day.
08-22-2013 11:44 AM
Sorry, I overlooked it.
I suggest rearranging your NAT statements so that the NAT Exempt appears above the dynamic NAT.
nat (inside,outside) source static inside-network-object inside-network-object destination static NETWORK_OBJ_192.168.250.0_25 NETWORK_OBJ_192.168.250.0_25
nat (inside,outside) source static management-network-object management-network-object destination static NETWORK_OBJ_192.168.250.0_25 NETWORK_OBJ_192.168.250.0_25
nat (inside,outside) source dynamic AllInside-networks interface
08-23-2013 02:48 AM
Executed the commands you suggested, still not able to ping to management interface.
08-23-2013 03:06 AM
did you remove the NAT statements before you issued the commands? It is easier doing this in the ASDM but will cause existing connections to be terminated, and those connections would need to be re-established.
08-23-2013 03:30 AM
Yes, i removed all NAT statements first, then i executed the ones you suggested. NAT looks like the folllowing in ASDM:
1 inside outside 192.168.1.0/24 192.168.250.0/24 any -- Original -- -- Original -- -- Original --
1 outside inside 192.168.250.0/24 192.168.1.0/24 any -- Original -- -- Original -- -- Original --
2 inside outside 192.168.100.0/24 192.168.250.0/24 any -- Original -- -- Original -- -- Original --
2 outside inside 192.168.250.0/24 192.168.100.0/24 any -- Original -- -- Original -- -- Original --
3 inside outside AllInside-networks any any a_u$c@1b2df369 -- Original -- -- Original --
