So I have a ASA I can connect via SSL perfectly fine receiving internet.My issue is that I cannot ping any device on the network especially the inside network on my router. My topology is a ASA 5505 - 1841 Router - 2960 switch - end devices I would like to be able to access my end devices via the VPN. Below is my ASA Config:

  • You should include the router configuration. You may have a problem, e.g. NAT, on the router, but we cannot tell. – Ron Maupin Mar 30 at 19:28

The problem is that your VPN terminates on the outside of the router inside-source NAT. To do what you want, you need to terminate the VPN on the inside of the router inside-source NAT.

In the case you have explained:

ASA 5505 - 1841 Router - 2960 switch - end devices

You would normally NAT on the ASA and not on the router, or you would terminate the VPN on the router or put the router outside the ASA. You should only use NAT where you actually need it, which would be between the public and private addressing.

Your problem is that the addresses inside the router inside-source NAT do not exist where the VPN terminates. Only the outside router address can be seen by the VPN end-point, and you would need specific NAT entries to allow access from the outside to the inside.


Also, the 11.0.0.018 network you use on the ASA does not belong to you, so you should not use that address range.

  • How would I start to do that? My apologies I just started working is Asas – andrewixl Mar 30 at 20:04
