Hello,
Sorry about the delay.
In fact the problem did not come from the configuration but simply from a DNS problem. I hadn’t paid attention, but the ping test was coming back to me from the IPs which does not concern my Network. The domain I thought was not used on the web is used. To make a test I tried to clamp PFSENSE so that it only gets my DNS from the AD without success.
I changed the name of my domain and this time I made sure it was mine.
Now it works out.
thank you for your help.
