# WireGuard Easy VPN — deployed on npm_internal behind NPM # WireGuard Easy VPN (v15) — UI at 10.10.0.36:51821 on npm_internal, fronted by NPM
# After first deploy, you MUST add NAT hooks in the wg-easy UI: # (vpn.boxswapper.io -> http://10.10.0.36:51821). Login: admin / wireguard_ui_password from vars.yml.
# 1. Open http://10.10.0.36:51821 in a browser # v15 init is ONE-TIME: the INIT_* envs below are consumed only when /etc/wireguard/wg-easy.db is ABSENT.
# 2. Log in with the username/password from vars.yml # Force a re-init (wipes clients + server keys): podman rm -f wg-easy && rm -rf /opt/apps/wireguard, then re-run.

"""Replace wg-easy iptables hooks with nftables equivalents.
wg-easy images ship iptables-legacy, which cannot initialize the `nat`/`filter`
tables inside a podman container netns on nftables-only kernels (fc42). Every
`wg-quick up wg0` then fails at the PostUp hook, so the wg0 interface is rolled
back and ALL client API calls 500 with "Unable to access interface: No such device".
The official wg-easy podman+nftables tutorial replaces the hooks with nft rules.
This script rewrites hooks_table in /opt/apps/wireguard/wg-easy.db when the hooks
still reference iptables. Run it with the wg-easy container stopped, then restart
the container so wg0.conf is regenerated. Idempotent.
