24.1 Production Series / Unbound DNS failure to properly resolve
« on: April 16, 2024, 08:34:49 pm »
I apparently have a lack of understand on how to make my unbound DNS to do what I want.
I have a unique setup I guess. I have two Synology NAS units. I wanted faster throughput so bought 2 10gbps NICS. I attempted to connect the high speed cable to my switch to only find out that even though it has 2 Fiber ports, they support 1gbps! WHY!? Dumb.. so as a work around, I have connected the cable directly from one NAS to the other. This is when my problems began. So to kind of draw a word picture:
NAS 1 has 2 IP addresses.
NIC 1 is on 192.168.100.x
NIC 5 is on 192.168.1.x (high speed)
NAS 2 has 2 IP addresss.
NIC 1 is on 192.168.100.x
NIC 5 is on 192.168.1.x (high speed)
All of a sudden my SMB server names started dropping out. I can still connect via IP, but when I drop to bash and ping from a workstation on the .100 subnet, NAS1 is is trying to resolve to NIC5!! I do not understand how this is even possible, but, if I ping NAS.FQDN, it resolves properly to NIC1.
So I went and added over rides in Unbound. I gave it the server name with proper IP address and that did not work. I then added under aliases the server name and still no go.
So what am I doing wrong? How can I get it to properly resolve everytime? I have tried under general to add A record registration, I have tried changing the local Zone Types, but nothing seems to work. I don't even understand how Unbound even knows those NIC5's exist, since they are not connected anywhere except to each other. I also tried making those NIC5 gateways each other.
