Alternative for L7 filtering

[tumbler]

hi,

i am wondering if there is a workaround to bypass the firewall filtering for certain applications.
you can do L7 filtering but this seems to be very cpu intensive and even if you can make it work
it seems only usefull for specific known communication protocols.
some apps (mostly some games) do mess up my basic firewall rules and i want to avoid that to some degree.

i was thinking of some client side program that would be able to layer any communication through the firewall for a specific authorised program
but my knowledge of this is a bit limited.

any feedback appreciated,
thanks,

You might be using squid as a proxy server with user authentication to work it out.
