Static IP Block / Nameservers for Unbound / Headscale / + More

[fakebizprez]

Hi,

I know there have been multiple posts on regarding AT&T's unconventional Static IP blocks, but I believe I have configured it correctly by creating a Gateway to match the AT&T Static IP Gateway, and a Virtual IP for each of the five usable Static IPs. ✅

For my Headscale client (open source Tailscale), if I want to use Unbound as the "Magic DNS" for the entire mesh network, I need to create a nameserver, using an FQDN, for the DNS. I have done so using Porkbun. ✅

This will be running off of a NUC, baremetal, with an IP address of 192.168.128.153. When I try to point that IP address to the new Public Static IP Gateway, I receive the following error:

Code Select Expand

The following input errors were detected:

The gateway address 99.35.XXX.XXX does not lie within the chosen interface's subnet.

I know the solution to this problem is probably simple, but I am spinning in circles here, probably doing more harm than good by tweaking settings so I figured I'd ask the community for help.

If there's any other information I can provide for you to assist me, I'm more than happy to. Thank you.
