Hi,
SG300-10 mode:layer 3
dns server:192.168.2.11
vlan1 192.168.2.0 ip:192.168.2.254 0.0.0.0 next hop 192.168.2.3
vlan2 192.168.50.0 ip:192.168.50.254
dns server table:192.168.2.11 (active)
Router(192.168.2.3) dst.address 192.168.50.0/24 gw:192.168.2.254
No internet
pc:
ip:192.168.50.10 192.168.2.10
gw:192.168.50.254 192.168.2.254
dns:192.168.50.254 192.168.2.254
If dns = 192.168.2.3 >> yes internet
I think there is something wrong with the DNS setting on the SG300?
Or I do something wrong?

Hello Vision100,
Unfortunately the SG300 does not provided DNS proxy features. It will do layer 3 routing and as you mentioned when you point it to an actual DNS server it does work.

You need to use an internal or extrernal DNS Server and configure it in your DHCP scope options. If you are using an internal DNS Server you need to configure forwarding to an external DNS Resolver.
