26.1 Series / OPNsense 26.1.3 / os-caddy 2.1.0: be aware of important upstream change
March 05, 2026, 10:13:38 AM
Dear OPNsense users,
this post is only to make you aware of an important Caddy upstream change that is carried with os-caddy 2.1.0 in OPNsense 26.1.3:
The "Host" header of the upstream connection is now set to the address of the upstream host ("{upstream_hostport}"). Before Caddy 2.11.0 it was set to "{host}".
This might bite you in case you are running the upstream servers in a DMZ, depending on your setup. This can be easily fixed by adding a new "Header" object that carries the value of {host}, and in the "Handlers" sections add this header to the reverse_proxy handler.
Upstream commit that introduced this change: https://github.com/caddyserver/caddy/pull/7454.

Have you tried toggling the hardware acceleration features? Specifically Interfaces → Settings → Network Interfaces.
