DNS issue (probably wrong parameter somewhere)

[mamaxFablab]

Hello,

I have the following configuration: OPNsense 25.7 on a X86 desktop
ISP <=> Shared LAN <=> OPNsense <=> internal LAN

From internal Lan I can successfully ping server on internet
The dig/nslookup request for a internet domain works fine and I get the proper IP
But If I do a curl or a http request from a web browser, the domain is not resolved.

I use DHCP/DSN Masq and unbound DNS
On internal LAN the OPNsense DHCP provide the OPNsense IP forthe DNS as expected

do someone couls tell me from where that issue could come?
