I am trying to configure a VPN for use with the Cisco VPN Client. I currently have the VPN operational but I am having trouble allowing access to multiple subnets that are connected to the ASA. My current VPN DHCP pool is 10.0.0.0/24. I want VPN users to be able to talk to one of my other vlans (172.16.20.0/24). This is what I can't figure out. If I change my VPN DHCP pool to something like 172.16.20.100-110 then I can talk to everything on that subnet fine. But as soon as I change the DHCP pool back to the other subnet then I can't. Any suggestions??
Here is my config:

If you chose to split the tunnel, please change to highlighted line below to split-tunnel-policy "tunnelspecified"
this is your current config.
group-policy SBOnet_VPN_Tunnel internal
group-policy SBOnet_VPN_Tunnel attributes
vpn-tunnel-protocol ikev1
split-tunnel-policy tunnelall
split-tunnel-network-list value SBOnet_VPN_Tunnel_splitTunnelAcl
Otherwise, if you chose to tunnel everything from the remote users', i.e. including remote-user's web-browsing traffic into the tunnel, then you could dynamic nat those traffic to your outside interface (backupisp), as shown below.
object network vpn-pool-nat
subnet 10.0.0.0 255.255.255.0
nat (backupisp,backupisp) dynamic interface
