[SOLVED] Question about Caddy configuration

[afX33800]

Hello,

I've a question about Caddy configuration.

I'm trying to configure on my opnsense (by the plugin), and I am searching about split DNS configuration.

For me I have to write a DNS override on Unbound, but what's is the target on A ?
A = 0.0.0.0 or on other address ?

tank's for your help.

Hello,

Thanks for your answer.

Just to be sure that I’ve a good understanding :

If I’ve domain.com, I setup a A record on my dns provider for subdomain.domain.com.
Then I setup Cname for app.subdomain.domain.com to my previously A record right ?

And no record on unbound.

But a point that I doublt. My reverse proxy hasn’t aim to serve app on external (or just one maybe). With this configuration when I try to Connect to app.subdomain.domain.com I will be see by OpnSense coming from external right ? So Acl to restrict to internal ip will always match so I Will never Access ?

Thanks for your informations

Yeah you understood right.

Just try it out. The ACL will match when your clients are in internal Networks behind the OPNsense (if you want to restrict access.)

The OPNsense will see the internal IP address reaching your external address.
