I have taken clientel from a company for online share trading whenever I got connected via Cisco VPN client 4.0.4 MY 2mbps Broadband internt connection bandwith entairly blocked regardless of any data transferred or not, cannot open google.com, even I tryied to open webpages using another dialup connection through 56.6 kbps telephone line with internal modem when already connected vpn through 2mbps broadband but no effect . Any idea how to get rid out of this situation. my another question is that will cisco vpn works behind poxy ?

I have to point out the reason for a VPN is to secure a connection between two trusted computers. Opening that up kind of defeats the reason. It can be done if you understand it is not secure. Depends on exact tunnel and proxy. I read it wrong and answer it wrong too. So get off my case you goober.

Yes. I think no such security is required because lots of people are doing same thing using different software but this trading application only runs under VPN,so if somebody help me to say how to allocate lteast half bandwith for this application as it could be run 28kbps bandwith, i heard split tunnelling is the only remedy but i don't have any knowledge.

Okay, check this... Mobile VPNs can essentially be set up in 1 of 2 ways... either forcing ALL traffic down the VPN... so the administrator can apply traffic rules, anti-virus, web-filtering, etc, to all of your traffic. OR only directing traffic destined for the corporate LAN through the VPN, while all other traffic (such as google.com) is allowed to got directly form your machine, out to the internet, unencrypted. If the VPN is configured to force all traffic through the tunnel, then the ACLs on the Firewall/VPN device will need to be edited, to allow your connections out. You really should check with your system administrator on this one. He/she is the one that can make these changes. Many times new employees have more restrictions on the network.
