I currently have a stack that I am trying to implement a local installation of fail2ban with [Vaultwarden w/MariaDB + Caddy (All 3 Docker Compose)]. I am having trouble figuring out jail.d configurations whether or not I should replace
banaction = %(banaction_allports)s
with something else since my instance is running running behind the caddy proxy.
Per the wiki.
NOTE: Do not use this if you use a reverse proxy before Docker container. If proxy, like apache2 or nginx is used, use the ports of the proxy and do not use chain=FORWARD, only when using Docker without proxy! NOTE on the NOTE above: That's at least not true for running on Docker (CentOS 7) with caddy as reverse proxy. chain=FORWARD is absolutely fine and working with caddy as reverse proxy.
Anyone know if I should be doing something different other than the below due to the NOTE on the NOTE.
action = iptables-allports[name=vaultwarden, chain=FORWARD]
Any help is appreciated.
