When I connect to my company network via cisco vpn client, it successfully connects and all the required applications Runs BUT
Internet traffic stops, resulting, No Browsing, etc etc,,,
Please advise, whether I need to check vpn client's configuration or do I need to add something in my cisco 2811 router,
There are two ways to achieve this. If you want your users to use their local ISP gateway, you will want to configure split tunneling for the client group. Split tunneling is configured on the router and identifies what networks are to be protected via the tunnel. Alternatively, you can tunnel all traffic from the client to the hub router when connected and then configure hairpin routing for Internet access. Below are sample configs of each.
