Cisco VPN Client and default gateway

mvoss · ‎02-15-2006

When I have users connect via the Cisco VPN Client they get a default gateway pointing to the network they connected to. I need to have their default gateway be whatever their PC was using before they opened the VPN connection. I can't find any option to disable this feature. As a result, once a user connects using the VPN client, he/she is unable to reach the internet or any other IP that is not on the VPN network. I tried to just delete the default route that the VPN client creates but that doesn't work.

Hello,

what you would need to implement is called split tunneling. All non-encrypted traffic is going to the local default gateway in this scenario. An example of how to conigure that is found in "Configuring Cisco VPN Client 3.5 and the Cisco Integrated Client to Secure Nonencrypted Traffic While Using Split Tunneling" at

Hope this helps! Please rate all posts.

That article only works for VPN clients connecting to VPN 3000 Concentrator; I have VPN Clients connecting to a 2800 Router.

below are the sample codes for configuring remote vpn access with split tunneling on router. in particular, the command "acl 130" under "crypto isakmp client configuration group vpngroup" and the acutal acl 130 are required for split tunneling.

aaa new-model

aaa authentication login vpnauthen local

aaa authorization network vpnauthor local

crypto isakmp policy 10

encr 3des

authentication pre-share
