SMB / conditional redirector

[d.simon]

Hello the team !

First, I'm sorry for the quality of my English.

I have a Freenas server and configured samba server with DNS server.
I would like configure conditional redirector :

for the domain : xxx.fr , use : x.x.x.x redirector
for the domain : yyy.fr, use y.y.y.y redirector
for all domains (Internet), use z.z.z.z redirector

I can do it in Windows Server, but I don't know if it's possible with Freenas server.

Thank you for your help
Sincerly
