Hi jan,
Thanks for the reply. Now mangle tables has this:
include/uapi/linux/netfilter_ipv4.h: NF_IP_PRI_MANGLE = -150,
What i get from this list that which table will get priority.
But i'm trying to know which function will be called first? I guess i
should build a demo module to test to see which one called first.
But i'm still confused about which function (one registered with
struct xt_target , another registered with struct nf_hook_ops) will
get priority?
How does a table associated with different chains?
