Specifying Address Translation Exception and Split Tunneling
Split tunneling lets a remote-access IPsec client conditionally direct packets over
an IPsec tunnel in encrypted form or to a network interface in clear text form.
The adaptive security appliance uses Network Address Translation (NAT) to
prevent internal IP addresses from being exposed externally. You can make
exceptions to this network protection by identifying local hosts and networks that
should be made accessible to authenticated remote users. (In this scenario, the
entire inside network 10.10.10.0 is exposed to all remote clients.)
In Step 10 of the VPN Wizard, perform the following steps:
Step 1 Specify hosts, groups, and networks that should be in the list of internal resources
made accessible to authenticated remote users.
To add or remove hosts, groups, and networks dynamically from the Selected
Hosts/Networks pane, click Add or Delete, respectively.
