Problem

All LXC containers on Proxmox use DHCP. After a power outage or reboot, IPs can change, breaking every service link in Dashy, Komodo, and bookmarks.

Adguard is currently at 192.168.1.86 (expected .95 — already drifted once).

Fix

Step 1 — Static IPs inside each PVE LXC

PVE web UI → select LXC → Network → edit eth0 → change DHCP to Static:

LXC	IP/CIDR	Gateway
actualbudget	192.168.1.209/24	192.168.1.1
beszel	192.168.1.189/24	192.168.1.1
adguard	192.168.1.86/24	192.168.1.1
audiobookshelf	192.168.1.201/24	192.168.1.1
plex	192.168.1.207/24	192.168.1.1
jellyfin	192.168.1.250/24	192.168.1.1
forgejo	192.168.1.240/24	192.168.1.1

Restart each LXC after saving. Nexus/PVE/PBS are physical — set via /etc/netplan/.

Step 2 — DNS rewrites in Adguard Home (192.168.1.86)

Filters → DNS Rewrites → Add rewrite:

Hostname	IP
nexus.lan	192.168.1.226
pve.lan	192.168.1.227
pbs.lan	192.168.1.223
forgejo.lan	192.168.1.240
nas.lan	192.168.1.217
actualbudget.lan	192.168.1.209
beszel.lan	192.168.1.189
audiobookshelf.lan	192.168.1.201
plex.lan	192.168.1.207
jellyfin.lan	192.168.1.250
pihole.lan	192.168.1.220

Step 3 — Point router DNS at Adguard

Verizon Fios router (192.168.1.1) → DNS:

Primary: 192.168.1.86 (Adguard)
Secondary: 1.1.1.1 (internet fallback)

Step 4 (optional follow-up) — Update Dashy to use .lan hostnames

After DNS is confirmed working, open a PR to update dashy/conf.yml replacing IPs with .lan names. That work is already started on branch feature/dashy-lan-hostnames.

No git PR needed

This is all UI/config work. No compose files change.
