Setting Ip Access Control - ADDER AdderView CATxIP 1000 User Manual

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
access control
for details about how to regain access.
