Discussion

The IPSec tunnel end points may be configured on the OOBM gateway routers connecting the managed network and the NOC. They may also be configured on a firewall or VPN concentrator located behind the gateway router. In either case, the crypto access-list used to identify the traffic to be protected must be a mirror (both IP source and destination address) of the crypto access list configured at the remote VPN peer.

Fix Text

Configure he crypto access-list used to identify the traffic to be protected so that it is a mirror (both IP source and destination address) of the crypto access list configured at the remote VPN peer.

Check Content

Verify the configuration at the remote VPN end-point is a mirror configuration as that reviewed for the local end-point.
