Cisco ASA AnyConnect Access Rule

I have a Cisco ASA 5510 that I can connect to using the AnyConenct VPN Client.

I am assigned an IP of 192.168.15.2

The outside interface of the ASA is 192.168.10.7

From 192.168.15.2 I can ping the ASA outside interface. However, if I try and ping another host (192.168.10.1) this fails. If I try and ping from 192.168.1.1 to 192.168.15.2 I get this error:

3      Mar 17 2011      20:43:06      106014      192.168.10.1            192.168.15.2            Deny inbound icmp src outside:192.168.10.1 dst outside:192.168.15.2 (type 8, code 0)

Should I "believe" that the IP assigned to me of 192.168.15.2 is indeed on the outside interface? I have no physical interface, or VLAN that is assigned a 192.168.15.x address

Is this an access or a NAT issue?

Thanks

you can safely believe that. the VPN is terminated on the outside interface so that's where it's origin is.
So you're trying to ping from another outside address? You are not trying to ping from the in to the outside?
If so, you could try to issue same-security-traffic permit intra-interface on the asa.

Yes, that is correct. My router sits outside, has an address on the same subnet as the outside interface of the ASA.

I will see if I can find where I add the command you suggested.

Thanks

Are you using the ASDM?

Device setup->interfaces->tick 'enable traffic between two or most hosts connected to the same interface'

I am using both ASDM and SSH .... I accessed via SSH, and in global conf mode simply added the command you suggested and I can now SSH to the router, ping to and from the router. Many thanks...this has worked.
