Here is the senerio. I have a Cisco 1811 router with VPN access. I am trying to set up the router so that I can access the network form outside. I can do that but once I connect to the VPN I loose all internet connectivity. I 've gather that I need to set up split tunneling to do this, but I am unsure how to set up split tunneling from CCP or CLI.
To configure split tunneling on a router.
access-list vpnacl permit ip 10.1.1.0 0.0.0.255 10.2.2.0 0.0.0.255
crypto isakmp client configuration group GROUPNAME
The above example, asigns ACL vpnacl to the crypto group (to enable split tunneling).
So, only traffic between the internal LAN 10.1.1.0/24 and the VPN pool 10.2.2.0/24 will be encrypted (sent through the tunnel).
If this router is also doing NAT, then you need to exempt from NAT this same traffic.
