Address by computer name instead of IP address in WireGuard VPN?

@johnc

Would these LuCI changes I’m making be reset if I hard-reset (10 seconds) the Brume 2?

It’s all in the HOW-TO.

[johnc]

Thanks for all your help, so far, but I’m still unable to connect at mac.local.

[johnc]

If I knew how to do this safely, on a mac, I would consider it… but the default/unchangeable computer name, through settings, must end in .local.

Can you ping your Mac via LuCI → Network → Diagnostics → IPv4 Ping w/ 10.0.0.2?

Good stuff. Can you ping your Mac via its WG IP (eg: 10.0.8.2)?

@johnc

WG’s tunnel address is 10.0.8.1/24

Reference(s):

Correct calculation of WireGuard client IP?

Thanks. Starting over this time yielded the results I was after. My lan still exists at 10.0.0.x; Brume 2 = 10.0.0.1 WG’s tunnel address is 10.0.8.1/24 (so as not to conflict with the default Open VPN server (which I am not using at the moment)) and I have both masquerading and Allow Remote Access LAN enabled. I took the defaults for the client config. With my iPhone disconnected from wifi, I connected to the VPN and could get to the Brume 2 admin page at 10.0.0.1. Not only that, but I could …

Also, I added both mac.local and mac.lan to my ‘hosts’ file

FWIW, I did these, also:

So we know WG is proper… which we already knew. What’s the result when you ping via the hostname(s) (eg: mac.lan, then mac.local)? I’m looking to see what IPv4 is returning.

I’m speculating if this will help but what happens if you set mac 10.0.8.2 as the mac.{lan,local} & remove all references to 10.0.0.2 in the GI GUI hostnames &/or LuCI Static Leases/Hostnames?

I’m wondering if that’ll be enough to resolve the DNS to the WG IP but I wouldn’t get my hopes up.

Please make sure you have a backup made first.
