Subdomains on DS220+ (LAN only)

[myStar]

Hey over there,

i have following issue, where i want to create a smooth and easy network flow and i am a bit stuck.

I have an Asus ax86u (MerlinWRT 386.3_2) running on 192.168.1.1. Netbios name for example https://router.homelan => works.
I have an Synology DS220+ (DSM7) running on 192.168.1.123. Netbios name for example https://device.homelan => works.

I want to acess for example Synology Calender.
The build in Adress is something cryptic like "https://synology.homelan/caldav.php/{username}.

Goal is to reach it via "https://caldav.synology.homelan".

I had already played around with reverse proxy & nginx reverse proxy in a docker, trying to reroute (especially because the ports-problem).

nslookup test.synology.homelan
Server: 192.168.1.1
Address: 192.168.1.1#53

** server can't find test.synology.homelan: NXDOMAIN

Nslookup tells me, that the request for "caldav.synology.homelan" is not even getting routed to "synology.homelan", because the router interprets it as a new host.

So in my perspective, i have 2 options:

1) adding (all subdomains /wildcard subdomains) in the router (hosts, dnsmasq.conf, [anywhere else])

2) running an own LAN DNS Server (for example on 192.168.1.123 [synology.homelan]), and use it here:

So. can someone agree? or are there better (already built in) options, i dont see?


And yes, this is just in LAN. I dont want to expose my Synology to the WAN (yet). Access over OpenVPN (on ax86u.home) with ddns is granted.



Thanks in advance

In the mean time, i tried something like this: https://www.stevenrombauts.be/2018/01/use-dnsmasq-instead-of-etc-hosts/. (creating a dnsmasq.d folder [with configs], and tell dnsmasq.conf to use it)

After reboot the config file was overwritten and the folder gone.

So, with a symlink to /rom i can persist the folder. but it would still get ignored due to the system "re-generating" the dnsmasq.conf file.

ideas ?

so, if any1 is facing this issue:

add something like

address=/.device.homelan/192.168.1.123

to

/jffs/configs/dnsmasq.conf.add
