Hi,

When a VPN client has an IP adres in the 10.xx.xx.xx range, the
connection to the BM is setup successfully, but the client cannot get
any further on our network. E.g. access to a mailserver on the
internal lan fails.

I guess it's a routing problem of somekind.

The BM has these IP adresses:
Private:192.168.203.254
172.18.10.1
Public: XX.XX.XX.82
Company backbone (marked as public): 10.9.33.2 (mask 255.255.240.0)
