Hello,
I am trying to figure out a way to force certain DNS names and traffic related to that "flow" trough VPN but im not sure if im doing it right - or if its even possible.
Config:
access-list VPN-SPLIT-TUNNEL standard permit 192.168.50.0 255.255.255.0
access-list VPN-SPLIT-TUNNEL standard permit 10.0.0.0 255.255.255.224
nat (OUTSIDE,INSIDE) source dynamic VPN-POOL interface destination static VPN-PAT-NETWORK INSIDE-LAN-NETWORK
nat (OUTSIDE,OUTSIDE) source static VPN-POOL VPN-POOL destination static VPN-POOL VPN-POOL
nat (OUTSIDE,OUTSIDE) source dynamic VPN-POOL interface
object network VPN-POOL
subnet 10.0.0.0 255.255.255.224
description VPN-POOL
object network VPN-PAT-NETWORK
subnet 192.168.50.0 255.255.255.0
object network INSIDE-LAN-NETWORK
subnet 192.168.0.0 255.255.255.0
webvpn
enable INSIDE
enable OUTSIDE
no anyconnect-essentials
anyconnect image disk0:/anyconnect-win-4.3.01095-k9.pkg 1
anyconnect enable
tunnel-group-list enable
group-policy HEMMA-VPN-POLICY internal
group-policy HEMMA-VPN-POLICY attributes
wins-server none
dns-server value 8.8.8.8
vpn-tunnel-protocol ssl-client
split-tunnel-policy tunnelspecified
split-tunnel-network-list value VPN-SPLIT-TUNNEL
default-domain value cristiannilsson.se
split-dns value www.google.se
address-pools value VPN-POOL
webvpn
anyconnect keep-installer installed
anyconnect ask none default anyconnect
Now if i remove the NAT statement
nat (OUTSIDE,OUTSIDE) source dynamic VPN-POOL interface
Connection to www.google.se dies when using VPN, related or not i cant say.
I hope i wrote in a way that anyone can understand :)
Regards,
Cristian

I think i have a way of doing this with access-list matching fqdn object.
Will update when tested.

This did not work, sadly:
object network FQDN-WWW.GOOGLE.SE
fqdn www.google.se
Ben-Dover(config)# access-list VPN-SPLIT-TUNNEL extended permit ip object FQDN-WWW.GOOGLE.SE any
ERROR: Access-list contains user, user-group, security-group or FQDN objects. These are not supported in group policies.
If anyone have a work-around it would be much apreciated.
