Suggestion for new versions: Color coding DHCP leases
-
Hello,
I would like to suggest a new feature:
When accessing the Status>DHCP leases a list of all DHCP leases is shown. A column is showin the status "online" or "offline". Having many devices listed here it is hard to get an overview which devices are really online or offline.
I'd like to suggest that the field online or offline is color coded. E.g. it could be green when online or red when offline. This would really improve the see the status of the system instantaniously.
Best wishes
Doc Alex

Given the inaccuracy of that column, that may not be a very useful addition.
If a device says "offline" it just means it has not tried to communicate through the firewall recently. It may still be online and running just sending no traffic or only local traffic.
The online/offline status is taken from the firewall's ARP table.

You can sort on the status column by clicking on the header, makes it a bit easier when the online and offline are grouped.
Looking at the previous answer I had a question, is there something you could run on your LAN to get all the active systems to appear in the ARP table? Maybe a broadcast ping or a quick scan with a network tool?

You can do an ARP scan in nmap (choose the interface, enter the subnet x.x.x.0/24, select ARP)
