Hello, I’ve set vlans on my omnia. In default vlan1 DNS works well but in vlan3 DNS does not work. I can access internet using IP addressess… However I need to use DNS in that vlan too. Does anyone have clue how to run it?
Check/uncheck DNS forwarding has no impact.
Thank you
Does LuCi -> Network -> Interfaces -> lan_studia -> DHCP Server -> advanced settings -> DHCP-options match:
6,<Omnia IP in VLAN subnet>
(See example below the field)
Edit: If this doesn‘t fix it make sure you can reach port 53 (DNS Port) Omnia‘s ip on VLAN subnet (e.g. using netcat). If it‘s not reachable a firewall rule is blocking access to Omnia‘s DNS Server from this subnet

Thank you very much. It was blank. Now DNS works well. I’ll google what that setting mean.
You‘re welcome ;). It tells clients via DHCP which DNS server they should use. I think it sends out omnia‘s default IP (on br-lan) even on other subnets if not set manually and this ip isn‘t reachable from other subnets
