ASA 5505 behind a Router, no access to internal Network

Bernd Windisch
Level 1
Level 1

Hello everybody,

have a little (or big) problem:

ASA 5505 behind a Router for VPN access;

* Ports 500, 4500 (UDP) are forwarded
* ESP is forwarded

My local network is 10.1.2.0/24; VPN pool on the ASA is 172.20.1.100 - 200/24

ASA IP: 10.1.2.230

Outside interface is not in use

On the Router  is a static route set up in the net 172.20.1.0 via GW 10.1.2.30

I can  establish the VPN tunnel using Windows or iOS clients;  i can ping from the VPN client the ASA - LAN interface (10.1.2.230), i can ping from the ASA the VPN Client 172.20.1.X

I can not ping the VPN client from hosts on the 10.1.2.x network, i can not Ping from the VPN client a 10.1.2.X host.

1000 thanks for any advice!

Here is my config:

do you have a route in your internal network to reach the vpn pool subnet

problem solved with
