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!
