# Deny

## Deny Permanently

The deny permanently area allows you to manage IP addresses that are permanently denied by the firewall.

> > > > > • CIDR addressing allowed with a quaded IP.
> > > > > • Only list IP addresses. Anything else will be ignored.
> > > > > • Advanced port and IP filtering is allowed.
> > > > > • Add "do not delete" to the comments of an entry to have `DENY_IP_LIMIT` not remove that entry.
