Hi, I’m working on improving the security of my home server.
I want to use the Bitwarden app and the Chrome/Firefox extensions outside my LAN, but I don’t need Web Vault at all. How do I block access to Web Vault from outside the LAN in the Caddyfile?
pass.my-domain {
@block_webvault_outside {
not remote_ip 192.168.1.0/24 10.8.0.0/24
# What should be there?
# path /admin* will lock only admin options
}
respond @block_webvault_outside 403
reverse_proxy vaultwarden:80
}
If you’re deploying Vaultwarden via docker, there’s an ENV to disable web vault
WEB_VAULT_ENABLED=trueSet to false and redeploy.
But that will also block my access to WebVault within the LAN
I personally don’t expose services like these to the Internet directly but rather put them behind a Wireguard VPN that I stay connected to while remote to be able to access local network resources and ad-blocking without actually exposing anything in my internal network except the Wireguard port.
That doesn’t work for everyone of course, but I personally would be really nervous exposing a service like Vaultwarden to the Internet without having it behind a VPN.
