You can set the mark one rule, then match on the mark using other
rules.

Dear sir,
thanks for reply.I have register netfilter hook
NF_IP_FORWARD and wrote the handler function
i want to forward the packet from my local buffer
where i have cached it. i saw one field in skbuff
structure. i.e. nfmark.
Is it possible to pass the mark value to module and
then use it to point skbuff->nfmark?this mark can be
any integer value ??
thanks in advance.
