hello,
I come to you because I have a problem with my router lab. (I am a student and I work out trying to make small Labs).
For my Labs, I use a router ASA5505 to set up a Cisco VPN server.
There is a remote computer with the Cisco VPN client that connects to the router through the Internet. It connects fine but I can't access internal resources on my network.
After days and days of research, I can not find where does the problem. I used Packet Tracer for determining the origin of the problem. This comes NAT rules and Access list.
I tried to put rules on the firewall and NAT rules set but I still can not.
Could you help me find what's wrong?
I've put below the router configuration. For information, I use ASA with ASDM Version 7.2 Version 5.2
Thank you,
Have a nice day,
Bests regards.
Yann
