We previously had a Checkpoint Appliance along with and ISA Server. We are doing some upgrades and it was decided that the Checkpoint Appliance would be replaced with the Cisco ASA 5510.
I now need to get this working and I have not a lot of experience with ASA. I have set up a test lab, with an ISA server and the ASA and I can get almost everything working. In that I can get internal clients to access the Internet and I can get Internet Users to access an Internal web server.
The configuration looks like this:
Now I want to set up VPN on the ASA but this is where the problem lies. I have going through the VPN wizard on ASDM and made sure there are NAT exemptions. The remote client can connect to the ASA and successfully create a VPN tunnel, but is unable to access anything internally. I managed to get it to ping the ISA server, but I can't get it to do anything else.
Now to make sure I have no problems with my ISA server I have added a PC between the ISA and ASA and it is able to access the internal network the way i want it to without a problem.
On the ASA I have also set up a static route so that all Tunneled traffic is to go to the ISA server, but still it fails to work! What am I missing?
Any help would be greatly appreciated! Excuse the mess of the Config attached as it is a testing config and I am trying everything I can to get it working!
