a route is added on the SSL VPN client in the Address field and the the
subnet mask for the destination network in the Netmask field, and then
click Add.
- Exclude Traffic: Allows you to exclude the destination networks on the
SSL VPN client. The traffic to the destination networks is redirected using
the SSL VPN clients native network interface (resolved through the
Internet Service Provider or WAN connection). To add a destination
subnet, enter the destination subnet to which a route is excluded on the
SSL VPN client in the Address field and the the subnet mask for the
excluded destination in the Netmask field, and then click Add.
- Exclude LAN: If you choose Exclude Traffic, click True to deny the SSL
VPN clients to access the local LANs over the VPN tunnel, or click False
to allow the SSL VPN clients to access the local LANs over the VPN
tunnel.
• Split DNS: Split DNS provides the ability to direct DNS packets in clear text
over the Internet to domains served through an external DNS (serving your
ISP) or through SSL VPN tunnel to domains served by the corporate DNS.
For example, a query for a packet destined for corporate.com would go
through the tunnel to the DNS that serves the private network, while a query
for a packet destined for myfavoritesearch.com would be handled by the
ISP's DNS. By default, this feature is configured on the SSL VPN gateway and
is enabled on the client. To use Split DNS, you must also have Split Tunneling
configured.
To add a domain to the Cisco AnyConnect VPN Client for tunneling packets
to destinations in the private network, end the domian name in the field and
then click Add. To delete a domain, select it from the list and click Delete.
STEP 6 In the Zone-based Firewall Settings area, you can control the access from the
SSL VPN clients to the zones over the SSL VPN tunnels. Click Permit to permit the
access, or click Deny to deny the access. By default, the access for all zones is
permitted.
NOTE The VPN access rules that are automatically generated by the zone-based
firewall settings will be added to the firewall access rule table with the
priority higher than the default firewall ACL rules, but lower than the custom
firewall ACL rules.
STEP 7 Click OK to save your settings.
