Title: Loading pftables from files
Post by: clopmz on August 07, 2020, 03:50:51 pm

Hi all,

 I have configured several pftables as external sources and I have scheduled several cronjobs to create/update these pftables and to store data in plain files. But how can I configure opnsense to read these files and insert data in the correct pftable every time fw start or restarts?

Thanks

Hi there,

https://docs.opnsense.org/manual/aliases.html

"External (advanced)

Externally managed alias, this only handles the placeholder. Content is set from another source (plugin, api call, etc)"

Thanks Franco,

 Is it the only option? I would like my pf tables be consistent when fw starts ... Using curl option, pf tables will be empty until scripts run ...

pfctl can help you:

Syntax may differ a little from OpenBSD to FreeBSD.

You can run system "start" hooks via:
