Hello,

Dnes mi dojde edna po-dobra ideq za broene na lokalen/remote traffic -
da se izpolzvat ne accounting a IN/OUT pravilata.

razlikata e che accountinga nqma jump-out, t.e. ako edin paket otgovarq
na 5 pravila, i 5-te shte go prebroqt. Vsicki drugi pravila se prilagat
samo po edno, i sushto imat broqchi za trafik.

kartinkata stava takava

# za celiq subnet <-> lokalno
ipfwadm -I -a accept -S 192.168.0.0/24 -D masq_host -W eth0
ipfwadm -O -a accept -D 192.168.0.0/24 -S masq_host -W eth0

# za vsqko IP
ipfwadm -I -a accept -S 192.168.0.2 -W eth0
ipfwadm -O -a accept -D 192.168.0.2 -W eth0
...
etc...
# i ako nqma policy deny/reject:
ipfwadm -I -a deny -W eth0
ipfwadm -O -a deny -W eth0

kato purvite pravila trqbva da se prilojat i za dvata adresa na
masq_host - istinskiq i v LAN-a
