we're working in an Windows AD environment with about 400 SSL VPN Clients. These are connecting fine and are able to reach all internal services BUT: how do we configure a correctly working reverse DNS?
We've set the request routes so our internal VLANS are resolved forward and backward. All fine.
But if we try to resolve a clients name over it's VPN IP address 10.80.x.x we get a NXDOMAIN error on the UTM.
How do we get the clients to correctly register themselves with our AD based DNS server and in a Reverse Lookup Zone which is hosted there?
