Sounds like neither your ISP nor Windows understand netmasks very well..

You can probably just cheat and use a netmask of; that will
put your gateway and your IP in the same subnet.  Having a reachable
gateway should solve your DNS problem.

Thank you for answers.
I have changed netmask to Now I can ping my gate a.b.c.86,
but can not ping my dns. This is same with Windows. My nslookup shows that
DNS works correctly.
I can not ping anything else behind my gate, which differs from Windows - I
can ping ex.
I can also use ftp and telnet. I can not check www, becouse I did not
install any browser (only basic installation using 130Mb HD).
I have started NAT with standard configurations showed in HOWTO. My home
computer - behind my router ( - can ping router and gate
(a.b.c.86) but nothing else.

What can I do now to make it work properly? I thing my NAT works OK and
problem is with right conecting the router to the internet.
