Re: VPN Clients not able to communicate with network behind ISA Server

I found out, why it's not possible to communicte with the 10.0.0.0/8
network:
The network relationship between the VPN Client Network and the internal
network was configured to "Route" by default. Since there was no route from
the 10.0.0.0/8 network to the APIPA address from the VPN Client the retour
packets were "misroutet".
Changing the relationship between the VPN Client network and the Internal
network to "NAT" solved my problem.
Are there any known issues about configured the network relationship between
VPN Clients and the interal Network to NAT ?
I want to use L2TP/IPSec VPN and PPTP VPN.
Further I want to use EAP TLS for VPN authentication and certificates for
windows domain smart card logon.
Thanks
