as far as my networking knowledge goes..... 0.0.0.0/0 is the same 0/0 is the same as "all" or "any" in firewall rules... broadcast address is normally a.b.c.255 (which is why u cant have a node with that IP) On Fri, 25 Jul 2003, Fernando Gont wrote:

I think this could only be possible on old BSD systems, that used zero's instead of one's for broadcast addresses. -- Fernando Gont e-mail: fernando () gont com ar || fgont () acm org --------------------------------------------------------------------------- ----------------------------------------------------------------------------
