Here's a #Linux #networking question for you: what's a lightweight way to allow an HTTP request to an arbitrary *user*-provided FQDN, but to prevent the connection being made if the FQDN maps to an RFC1918/private IP address?

(The relevant command here is #curl, but I don't think that matters as it doesn't appear to have a flag to say "only connect if the IP is /not/ inside these subnets".) #sysadmin #devops #network #hostnetworking #sre #systems #platformengineering

After some days of troubleshooting FreeBSD networking and pf firewalling (and learning a lot in the process!), I finally made an article about FreeBSD VNet jails behind a dedicated firewall jail, that works with both IPv4 AND IPv6:

Internet <-> firewall-jail <-> application jail

I hope, someone might find that helpful. The detailed article is here in my Codeberg gists:

https://codeberg.org/Larvitz/gists/src/branch/main/2025/20250517-FreeBSDFirewallVnetJail.md

My next step is trying to get IPv6 address support into the marvelous tool jmore from @vermaden and sending him a pull-request for that :)
