says that different VLANs can use different DNS servers. The Firmware v7 manual does not address the issue at all. I tried to have a VLAN with unique DNS servers and it only half worked.
A windows 10 machine connected to the VLAN with DHCP shows the configured DNS servers (220.127.116.11 and 18.104.22.168) are in play (see above). But assorted online DNS server testers
all indicate they are not being used.
My guess is this a documentation oversight rather than a bug. DNS forwarding is enabled, so the two features are in conflict. DNS forwarding wants to use the router as a DNS server and the VLAN wants to use 22.214.171.124 as its DNS server.
Running firmware 7.0.3 on a Surf SOHO HW2.
If this is is working as intended, then pleeeeeeeeeeze update the manual and the router web interface.
