Re: VPN Client with ASA; Discarded packets on VPN Client
the configuration for remote access is simple like that.
tunnel-group XYZ type remote-access
tunnel-group XYZ general-attributes
tunnel-group XYZ ipsec-attributes
From the VPN Client, i can access the other site-site VPN subnets that are terminating on the firewall but cannot access the local subnets connected to the firewall interfaces. This seems to be very strange.
Any idea, what will be the problem.
