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?
