Re: About Classifier

I would use a config like this:

Classifier(12/0800)
-> CheckIPHeader
-> IPClassifier(proto IP-ENCAP) // you could also use the value "4" instead
of "IP-ENCAP"

If you then wanted to do things with the encapsulated IP packet, you could
do something like

-> StripIPHeader
-> CheckIPHeader(0)
-> IPClassifier( ...)

Hope that this helps!
