Hardware Version: V5
Firmware Version:

If you go to the Settings tab and select "Wired Networks -> LAN" and then edit one of the networks, there's a section where it (optionally) asks for a Domain Name. The SDN manual does not explain what setting this value accomplishes. Does anyone know what the purpose of this field is for?

If you set a domain as LAN in this section, you can use the domain not an IP to access the device which obtained the IP from the interface.

So, if I understand correctly: I set the domain for both LAN and VLAN10 to lan[dot]example[dot]com Then from PC1 I can refer to PC2 using PC2[dot]lan[dot]example[dot]com ? No need for a DNS server?

Ok, tried it and does not work unless I set a DNS server. By then, setting the domain name on Omada does not provide an advantage. Or am I missing something?

If you need to use domain to access each other across the VLAN, need a mdns setting.

Right, I also set mDNS for all the VLANS wink

I think this works as a search domain.

For example, if you enter yourdomain[dot]com in the domain field this will get passed down to the clients. 

I you then try to ping PC1 from the client it will automatically convert this to PC1[dot]yourdomain[dot]com, the DNS record still has to exist on the DNS server.

First of all I had to replace the dots in the addresses with something else as this forum keeps rejecting my post, doh!

 

Having fun with DNS LOL...

 

  • Router LAN and VLANs have domain set to lan•example•com
  • Router LAN and VLANs have DNS records pointing to my NAS (192•168•10•2)
  • I even named clients on Omada, for example Camera for a given MAC address but I doubt it's for anything else but the display in Omada
  • Named the device, for example EAP for my access point device in Omada
  • Cloudflare DNS for example•com to my WAN
  • On Cloudflare, set a CNAME *•example•com
  • I have a reverse proxy on my NAS
  • My local DNS server (on my NAS) have a zone for lan•example•com
  • I also added a *•lan•example•com A record in my local DNS to point to my NAS for the reverse proxy to do its job


Now, on a PC

 

  • I see that it's having a Connection-specific DNS Suffix with value lan•example•com coming from the router I believe (IPConfig /all)
  • I can ping a server from the reverse proxy, for example test•lan•example•com
  • Pinging eap•lan•example•com resolves to my NAS, probably because of the NAS DNS rule *•lan•example•com and not to the named device on omada
  • Same for pinging EAP, resolve to my NAS as eap•lan•example•com
  • Pinging another PC by name or FQDM gets resolved by the NAS proxy 😕
  • Going with NSLOOKUP, now we enter strange lands
    • DNS server is recognized as what I entered in Omada for the VLAN: 192•168•10•2 (my NAS)
    • Querying for:
      • MyPCName gives MyPCName•lan•example•com 192•168•10•2 (my NAS) 😕
      • MyPCName•lan•example•com gives MyPCName•lan•example•com•lan•example•com 192•168•10•2 (My NAS) 🤪
      • test gives test•lan•example•com 👍
      • Any entries from the NAS DNS gives the address it is configured to 👍
      • test•lan•example•com gives test•lan•example•com•lan•example•com 🤪
      • google•com gives google•com•lan•example•com 🤪


Surely I have configured something wrong but out of ideas for solving this
