Two controls added in Korthveil 1.1.21:

Never locked out (trusted sign-in sources)

Korthveil blocks sign-ins after five wrong passwords in 15 minutes, both for the account and for the address they came from, for 15 minutes. This stops password guessing. It can also lock you out of your own firewall after a few typing mistakes.

Addresses you list as never locked out are not blocked. Each wrong password from them still waits 2 seconds before the answer, so guessing from there stays slow.

  1. System › Administration › Management access.
  2. Under Never locked out: sign-ins from these addresses or networks, enter one address or network per line, IPv4 or IPv6, for example:
  3. The panel shows the address your browser connects from and whether it is in the list.
  4. Press Save to pending changes, then commit.
Management access: allowed sources and never-locked-out sources

Good to know:

Renew address and Reset port

Network › Interfaces, zones & routes › Interface configuration. Each enabled port has buttons at the end of its row:

Button Shown on What it does Traffic
Renew address (circular arrows) Ports that get their address by DHCP, such as the internet port Asks the DHCP server (your ISP's modem) to renew the address now. The answer arrives within a few seconds; the address under IPv4 is updated Not interrupted
Reset port (power symbol) Physical ports and VLANs Takes the link down and up again. On a DHCP port it then asks for an address, with the method that worked last time Stops on this port for a few seconds
Interfaces: Renew address and Reset port

When to use them:

A message above the table says what was done; every press is recorded in the system log with your name.

Failover pair: the standby holds its internet port down while it is standby (see Two firewalls with automatic failover), so pressing them there does nothing for the internet. Use them on the active firewall.
