yep.. found that. in ../linux/include/firewall.h
#define FW_BLOCK 0
#define FW_ACCEPT 1
#define FW_REJECT (-1)
#define FW_REDIRECT 2
#define FW_MASQUERADE 3
#define FW_SKIP 4
----------------------------------------------------
so when it refers on X rule in /proc/net/ip_forward|input|output, it
refers to those rules in fact?. Hmmm.. Wonder what FW_SKIP mean then?
disabled forwarding packets *(skip)*, what FW_REJECT would mean..
and another question:
If i have binary of the kernel running on some system,, but don't have
source code (where i could have a look in config file). How do i figure
with what options/modules enabled/disabled it was compiled, is there a way?
