Cisco ASA 5505 L2TP VPN cannot access internal network

Question

Hi,
I'm trying to configure Cisco L2TP VPN to my office. After successful connection I cannot access to internal network.
Can you jhelp me to find out the issue?
I have Cisco ASA:
inside network - 192.168.1.0
VPN network - 192.168.168.0
I have router 192.168.1.2 and I cannot ping or get access to this router.
Here is my config:

Thanks for your help.

Answer 1

You have to test it with "real" traffic to 192.168.1.2 and if you use ping, you have to add icmp-inspection:
policy-map global_policy
  class inspection_default
    inspect icmp
