DNS and DHCP -> using different domains for each network - Bug #1819 - $150
-
@CubedRoot yeah run in the same problem during evaluation and after googling was surprise to find that it's been reported 8years ago.
-
@Derelict Thank you for such comprehensive answer, it really helps to understand complexity of the problem on netgate side and timeline for resolution.

This post is deleted! -
Bumping this to let devs know a fix would be very much appreciated.
-
+1 I have quite a few SG1100 around at remote customer sites. It would simplify my usecase considerably if this quite natural way automation between DHCP and DNS was implemented.

@CubedRoot
Probably your issue is solved already, but for anyone looking at this, I am using pfsense 2.4.5 and have only 2 ethernet ports one for WAN and one for LAN and a VLAN.In the pfsense GUI go to :
-Services/DHCP Server/LAN
-Other options, the second option is "Domain Name" in my case lan.internal-Services/DHCP Server/IOT (in my case this is my VLAN)
-Other options, the second option is "Domain Name" in my case crap.internal-If you wanna test them just disable and enable your adapter options on your computer
-run cmd "ipconfig /all" and you should see the new domain name.Leave the default domain of pfsense as localdomain, since that will tell you that something is wrong for other devices.
-
@cubedRoot I am not sure what the difference is, but it is not working for me. Maybee a limit on how many sub leves the resolver can handle, or am I not allowed to use a real domain?
I have my real domain as vink-slott.dk and would like my internal stuff on [device].int.vink-slott.dk and guests computers on [guestdevice].guests.vink-slott.dk and so on. I have set Other option -> Domain name as described - and under General only the main domain. Everything stil end up under the main domain set under general.
-
This issue is still present in 2.4.5_p1.
I have three interfaces, WAN, LAN, and OPT with DHCP Server enabled on LAN and OPT with different domains provided in the options. All leases still resolve as the domain provided in the general system setup, ignoring the DHCP Server settings.
Why provide the option if it is not respected?
-
I've been wondering this the last couple days why this wasn't working, and did what you said, and bingo, it's all showing now!
Well done!
Edit: I think it may just take a long time to propagate. I changed all my subnet domain names now, and reset all the states, and rebooted the router, and it's still not showing. I'll bet it starts showing sometime in the morning...
-
I can confirm if anyone else is having this issue that the new domains did propagate overnight and are now showing correctly in pihole and ipconfig /all. It just took a while.
Now if I can just get my domain names to show on the VPN clients that connect to my OpenVPN server, I'd be a happy camper (at least as far as pfSense is concerned...)
-
@hockeyfreak I think you misread the post. This original issue wasn't about the DNS hostname on the DHCP lease, but rather the registration of the host and domain in the DNS resolver. This doesn't appear to work as the OP suggested is should.

I can confirm it's still not working in current 2.5 Release.
-
still not working... i have several sub-domains on my vlans and need a working reverse-lookup.. right now reverse-lookup returns general domain-name from settings..
-
+1 here.... I just want to have a subdomain for my VLAN, and even specified in the DHCP, it still only resolve as the primary domain in general setting.
I checked
/var/dhcpd/etc/dhcpd.conf, it has my subdomain specified under the subnet group.[ADDED]
I just tested by specifying a static IP/MAC mapping with the subdomain. Doing nslookup now report correctly...
-
- No go in 2.6, old guy still hoping for a solution
-
I wonder what that $150 should be now after inflation
Either way, also not having any luck with this. I'd love to see this as it'd be a big boon to treating servers as cattle rather than pets, which DHCP enables. and appropriately accessing servers that need interfaces in multiple networks for network segmentation.
-
Since ISC-DHCP Server is EOL , i'd not expect Netgate to spend a lot of time o adapt it to "multi domains".
The "obvious" replacement would be ISC KEA, and probably what Netgate would implement in a future release.Maybe they'll look at "multi domain", when implementing the new DHCP server.

That is almost always a bad idea. Unless this other network on the multihomed server is just a SAN network.
Servers with legs in multiple segments pretty much defeat the whole purpose of firewall between your segments.

I hope that it taken into consideration when ISC-DHCP is replaced. ISC-DHCP in it self, has been able to handle multiple domain all the time.
Anyway, all my SG-1100 boxes are nearing end off life to, so I maybe I should look into alternatives.
