I can not get nDPI compiled under Debian wheezy:

NDPI_PATH=/usr/local/src/DPI/nDPI make
if test -d ndpi_cpy; then \
                cp /usr/local/src/DPI/nDPI/src/* ndpi_cpy -R; \
        else \
                mkdir ndpi_cpy; \
                cp /usr/local/src/DPI/nDPI/src/* ndpi_cpy -R; \
        fi
make -C /lib/modules/3.2.0-4-amd64/build M=$PWD;

Google does not help. So I stay with the u32 solution for now. Back to my main question: What should nexthdr+X look like to do the same as „at 28“?

Thanks in advance
