Is there such a thing as a 0.0.0.0 netmask? If so, what would be the / notation? I'm transposing firewall rulesets from Gauntlet to IP Filter and the Gauntlet rules have some entries with a network address of 0.0.0.0 and a netmask of 0.0.0.0. alan _________________ *Alan Rubin* Sun/Unix/Networking/Web Writing Email:rubin at ezy.net
