I've got a very simple question, which seems to be extremely difficult when put into practice.

I have a Cisco IOS router with two Internet links (one over a WAN, through a proxy, everywhere, etc.) the other direct Internet.

Most traffic destined for the internet goes through the proxy over the WAN.

I want Skype traffic (why the client uses skype, I don't know..) to go out of the Internet link, while the rest of the traffic goes over the WAN through the proxy, etc.

Apparently skype is very difficult to detect/classify because of it's many adaptations to being blocked.

Is there any way to identify Skype on an IOS router (2911), and set it's next hop IP/interface?

Thank you, Aaron
