Pfsense and windows domain
-
My local network provide a domain using windows server 2019 , when I connect internet from pfsense the domain become unavailable and and the internet take over, I would like to know how to solve this issues.
-
What exactly are you seeing? How are you testing?
I would guess that you are switching DHCP to pfSense and that is passing it's own domain to clients. You can configure dhcp in pfSense to pass whatever you need though. Or not use dhcp in pfSense at all.
-
Another possibility is resolution of the Windows DNS domain...add a Domain Override on pfSense pointing to the IP(s) of the domain controller(s).

@stephe! We have LAN with windows server machine running and providing DHCP and DNS plugged on the switch, internet from pfsense plugged on the same switch as well client. What happens the time we plug pfsense LAN on the switch the LAN(domain) become inaccessible and the internet connection running normally. I would like the internet and domain work together.

@SteveITS Thanks, I have already done it from pfsense.
-
@fladias did you disable DHCP server in pfSense?
-
@SteveITS I will verify and give you feedback thanks!

How are you seeing that appear? How are you testing?
If you are not using pfSense as a DHCP server or DNS server then nothing should change when it's connected.
-
@stephenw10 from the client computer bottom right network icon notification as well as on shared drive accessibility it becomes disable.
-
So what's changing on the client? It's default route? It's DNS server?
-
@stephenw10 that is clear, without activating DHCP in Pfsense do you believe client still gonna have internet access?
-
It will if your domain controller is passing pfSense as the default gateway to clients via it's DHCP.
OK so you said you were not using pfSense for DHCP but if in fact it's still enabled there then that explains the behaviour you're seeing. Clients will get a dhcp lease and routing dns info from pfSense and lose whatever info the DC is passing them.
-
@stephenw10 I have noticed IP is different the one from pfsense when plugged, when I unplugged pfsense client use other IP from the domain.
-
Yeah you cannot have two DHCP servers. You must choose one and I would use the DC for that. Configure it o use the same subnet as pfSense and pass the pfSense LAN address as a default gateway to clients.
