VPN users can not communicate with the internal network

Hi all,

I have two ASA 5515 configured in failover (active / standby).

I used the ASDM wizard to create connections through ipsec cisco client.

Currently users are able to connect but can not do a ping to anywhere inside the network.

The ping request is received from the internal client but the internal client can not communicate with the remote user.

The ping fail also directly from the ASA.

When the remote client is connected an entry is added to the routing table:

S 192.168.10.130 255 255 255 255 [1/0] via <ip of the ISP>, "WAN"

as if that IP was reachable directly from the Internet.

I tried changing the settings of the NAT but in no way I can make them communicate.

The ultimate goal would be to create different users with different access permissions to the LAN and the other subnets in the company.

Thanks in advance for your answer

How is the NAT configued? Sounds like it is confused on what IP it should be sending that to. Also can you give us more config info.

This is my situation:

3 interfaces connected

- WAN (public IP)

- LAN (192.168.10.0/24)

- Remote LAN devices connect via wireless (192.160.20.0, 192.168.30.0, etc.)

Here is an extract from the command sh run:

interface GigabitEthernet0/0

nameif Internal

security-level 100

ip address 192.168.10.251 255.255.255.0 standby 192.168.10.252

The ultimate goal would be that a user is connected to the VPN-MY can communicate with the LAN and the Remote LAN.

Then create other tunnel in which users can access only to some remote LAN (maybe this is possible via ACL)
