OOoo my god, i found at http://www.batch.com/netmask.html how works subnet
(nothing easy!!!!)...  I asked small question but answer is veeeery long...

Now I know why should be gateway address between 213.215.114.65 and
213.215.114.94 but why is it working without monowall ? ...gateway is
213.215.114.1

Ok, now i start understand what can be wrong. The gateway which give me my
ISP isnt propably correct. (but why is my conection working without
monowall? is it normal?)

And next question, how you know that:

> With the address of 213.215.114.87/27, your upstream gateway device
> needs to be an address between 213.215.114.65 and 213.215.114.94
> excluding 213.215.114.87.

ISP give me 213.215.114.1

Which math are You using?  :-)   (sorry but Im very newbie)
I want know it because if i ask my ISP and he will telling somethings else i
can disagree... but now its difficult because i dont know the correct
settings for gateway.
