Two questions re Adguard

[iamgigglz]

I've setup up AdGuard Home in container in Proxmox. It's serving as DNS and DHCP server (everything on static leases) and seems to be working well.

First thing:
I'm trying to set up persistent clients using mac addresses rather than IP addresses, which Adgaurd claims to support, but it's not recognising MAC address clients at all.
These two rows are the same device...

Second thing: I have brief power failures more often than I'd like. It takes a minute or three for my proxmox server to boot up and all the containers to boot up. In the meantime I won't have a DHCP server. Surely that'll cause problems for devices that "boot up" faster than Adguard? Is this actually a problem or am I overthinking it?

I've not used AdGuard so can't answer the first question, but on the second one if you're using static assignments for everything then why not give them static IP addresses rather than using DHCP?

Yes, if AdGuard is taking a while to start you may have issues but you'll have no working DNS either at that point so lack of DHCP at the same time is likely not too much of a problem.

Clients don't lose their IP when the DHCP server is unavailable, they'll keep hold of until the DHCP lease expires though they'll often ask the DHCP server if the IP they have is still valid. An interface state change would likely trigger a DHCP request so if the switch that a hard wired device is connected to power cycles or the AP loses power then lack of DHCP will be a problem.

Some devices (like the Sky Stream puck and some IOT devices) simply don't offer the option.

If the two clients are the same device, AGH will be prioritising identifying the client using its IP and thus the second/redundant entry shows no activity. Delete the duplicate entry, edit the first and add a second identifier (the MAC) and you should be good to go.

As for power cuts, the same goes for your router and other electrical devices I assume? You're overthinking it. A device looking for an IP will periodically broadcast a DHCP discover request until the server pings back a reply once it's online. You should be fine.

Edit: Like this.

I had it with only the mac address entry for a while and it wasn't working at all. I then added the IP address entry and it picked up on that.
Honestly I'm no longer too bothered really. I've managed to put every device on my network onto a fixed lease so they'll always have the same IP address. Next step is to set permissions appropriately, and setup something that restricts the access anything new/unknown has.

As for power cuts ...<snip>... You're overthinking it.

I tend to. Thank you.
