Quick Answer

Back up your router’s VPN configuration by exporting settings through the admin panel (GL.iNet: System, Backup/Flash Firmware, Generate Archive), then separately saving WireGuard or OpenVPN config files, private keys, and your DDNS hostname and credentials. Store one encrypted copy in cloud storage and one offline.

Inventory: VPN profiles, private keys, DDNS settings, firewall and kill-switch rules, WAN and WiFi basics.
Keys: configs can be regenerated; a lost private key means re-issuing keys on every peer, so export them explicitly.
Encrypt: zip the bundle with AES-256 and never store keys in plain text; no notes apps, no camera roll.
Drill: test the restore once at home; backups are model-specific, and firmware mismatches cause partial restores. HomeIPVPN maps out a backup routine for your actual gear in a consultation.

How to Back Up Your Router's VPN Configuration

Your travel router holds the keys to your digital home: WireGuard private keys, server addresses, DDNS credentials, firewall rules, and kill-switch settings. Lose the router to theft, a failed firmware flash, or a factory reset, and rebuilding all of that from memory, from a hotel room, under deadline, is miserable. Learning to backup router VPN configuration properly takes twenty minutes once and saves you hours of panic later.

What to back up: configs, keys, DDNS settings

A router backup isn't one thing, it's a small collection. Miss one piece and the restore fails in a confusing way. Here's the full inventory:

VPN server/client configurations. Your WireGuard .conf files (or the router's VPN profile exports), including peer public keys, endpoints, allowed IPs, and pre-shared keys. For OpenVPN, the .ovpn files plus any ta.key or certificates.
Private keys and certificates. These are the irreplaceable part. Configs can be regenerated; a private key that's lost means re-issuing keys on every peer. Export them explicitly, some backup archives include them, some don't.
DDNS settings. Your provider, hostname, username, and update credentials. If the DDNS updater breaks after a restore, your travel clients can't find home.
Firewall and kill-switch rules. Custom firewall zones, port forwards (like your WireGuard UDP port), and the VPN policy/kill-switch configuration that forces traffic through the tunnel.
Network basics. WAN settings (DHCP/PPPoE credentials if your home router uses them), WiFi SSIDs and passwords, admin password, and any static DHCP leases your home server depends on.
A plain-text runbook. A short note describing what connects to what: which device is the server, which are clients, the DDNS hostname, and the restore order. Future-you, stressed in a foreign timezone, will thank present-you.

GL.iNet backup and restore walkthrough

GL.iNet routers (running their OpenWrt-based firmware) make this straightforward:

Creating the backup:

Log into the admin panel (usually at 192.168.8.1).
Go to System → Backup / Flash Firmware (in newer firmware: System → Upgrade, or the Backup section under System settings).
Click Generate Archive to download a .tar.gz of your current configuration.
Separately, go to the VPN Dashboard and export each WireGuard/OpenVPN client and server profile individually, keep these .conf/.ovpn files alongside the archive.
Screenshot or copy your DDNS settings page and firewall custom rules.

Restoring:

On a fresh or reset router of the same model, log into the admin panel.
Go to the same Backup section and upload the archive to restore settings.
Re-import VPN profiles if they didn't come back with the archive.
Reboot, then verify: tunnel connects, IP check shows home, DNS resolves through the tunnel.

Important caveats:

Backups are generally model-specific. An archive from one GL.iNet model may not restore cleanly onto a different model. If you travel with a spare router (wise), make it the same model or keep separate backups per model.
Firmware version mismatches can cause partial restores. Note the firmware version in your runbook and back up again after every firmware update.
The archive may or may not include private keys depending on firmware version, that's why you export VPN profiles separately. Never assume; verify by checking the archive contents once.

Storing backups securely off-site

A backup sitting only on the router it backs up is not a backup. And a backup containing private keys sitting in plain text in your email is a liability. Do both halves right:

Encrypt the bundle. Zip the archive, configs, keys, and runbook with a strong password (7-Zip AES-256 or equivalent). Your VPN keys are credentials, treat them like passwords.
Cloud copy. Store the encrypted bundle in your usual cloud storage. It's reachable from anywhere, which is the whole point.
Offline copy. Keep a second copy on a USB drive or in your password manager's secure file storage. Cloud accounts get locked too.
Don't store keys in plain text anywhere, no unencrypted notes apps, no screenshots in your camera roll, no pasting into chat messages.
Version your backups. Name files with dates (router-backup-2026-10-23.tar.gz). After any config change or firmware update, generate a fresh backup and retire the old one.

The restore drill (do this at home, once)

The backup you haven't tested is a hope, not a plan. Before your next trip: factory-reset a spare router (or your travel router, if you have time before departure), restore from your backup, and confirm the tunnel comes up. This single drill catches the classic failures, missing keys, wrong firmware, DDNS credentials that changed, while you're still home to fix them.

FAQ

How often should I back up my router configuration? +

Back up after every meaningful change: new VPN profiles, firmware updates, firewall rule changes, DDNS provider switches. At minimum, refresh the backup before each major trip.

Can I restore a backup onto a different router model? +

Sometimes partially, but don't count on it, especially across brands or between OpenWrt-based and stock firmware. Keep per-model backups, and if you carry a spare travel router, make it the same model as your primary.

Do GL.iNet backup archives include WireGuard private keys? +

It varies by firmware version, which is why you should export VPN profiles separately rather than trusting the archive alone. Verify once by inspecting a backup, then keep the separate exports as standard practice.

Where should I keep the backup password? +

In your password manager, the same one you'd use to recover it from the road. Don't put the password in the same cloud folder as the encrypted bundle.

What if my router is stolen mid-trip? +

With a good backup: buy or borrow a compatible router, restore your encrypted bundle from cloud storage, re-import VPN profiles, and you're back online. Without one: you're rebuilding keys and configs from scratch, and you'll need someone at home to re-issue server-side keys. This is the scenario backups exist for.

Should I back up my home VPN server too, or just the travel router? +

Both. The travel router is the urgent one (it's what you carry), but the home server holds the other half of the key pairs and the DDNS/firewall configuration. Back up both, store both off-site.
