Setting IP access control
The.golden.rule.with.this.feature.is.‘Include.before.you.exclude’.or.to.put.it.
another.way.‘Arrange.allowed.addresses.in.the.list.before.the.denied.addresses’..
This.is.because.the.positions.of.entries.in.the.list.are.vitally.important..Once.a.
range.of.addresses.is.denied.access,.it.is.not.possible.to.make.exceptions.for.
particular.addresses.within.that.range..For.instance,.if.the.range.of.addresses.
from.A.to.F.are.denied.access.first,.then.the.address.C.could.not.be.granted.
access.lower.down.the.list..Address.C.needs.to.be.placed.in.the.list.before.the.
denied.range.
IMPORTANT: This feature should be configured with extreme caution as it is
possible to deny access to everyone. If such an error occurs, see
for details about how to regain access.
