Let's Encrypt certificates for a machine behind IPFire IPS

1

Hi,

I have an Ubuntu 24.04 server using let’s encrypt certificates behind an IPFire (ver 199) firewall.

The renewal on Ubuntu machine is working with certbot http challenge till I activate the IPS system (in IPS mode) with the Emergingthreats.net Community Rules (all selected) activated.

Could you please help me find a way (whitelisting or other) to overcome this problem?

Thanks in advance

You should find what IPS rule is blocking cert reneval from Log → IPS Logs.

Then you have to customise ruleset for your needs. www.ipfire.org - Intrusion Prevention System (IPS)
