I have a little stupid problem with my easy VPN Server. I took the following configuration to configure the VPN: Click
I can successfully ping 192.168.99.1 but when I start AnyConnect (enter this IP-Address as serveraddress) on my IPhone, it first says that the server certificate is not valid (I ignore that because it is self signed..) and when I press continue it says that no connection could be established.
It's very likely that you don't have a PAT-pool configured and just use the "overload" keyword when NATing to your outside interface. In that command you reference an ACL (or an ACL in a route-map) where you have to make sure that your VPN-pool in included in the NATed traffic.
