In rules, to allow traffic TO my box from the lan 10.0.0.0/32
1 ipt -A INPUT -s 10.0.0.0/32 -m state --state NEW -j ACCEPT
2 ipt -A INPUT -s 10.0.0.0/32 -m state --state ESTABLISHED -j ACCEPT
3 ipt -A OUTPUT -d 10.0.0.0/32 -m state --state ESTABLISHED -j ACCEPT
Now, to allow traffic FROM my box to the lan 10.0.0.0/32
4 ipt -A OUTPUT -d 10.0.0.0/32 -m state --state NEW -j ACCEPT
5 ipt -A OUTPUT -d 10.0.0.0/32 -m state --state ESTABLISHED -j ACCEPT
6 ipt -A INPUT -s 10.0.0.0/32 -m state --state ESTABLISHED -j ACCEPT
The 3 and 5 rules are exactly the same. Is there a way to
discriminate this or the things are just like this and there is
nothing to do about it?
Tnxs in advance.
btw 10.0.0.0/32 ?!
Yeah.. what? I make my 10.0.0.0 subnet a class C :) It's Ok to do
that, try it!! :P
You probably mean 10.0.0.0/24 then ?
