I chose "Use these Servers" in the WAN1 config and entered local DNS servers. The WAN1 is PPPoE and ignores the static settings and displays the nameservers from the ISP. Any suggestions on how to fix this?
Actually what I am focusing on is the WAN1 connection. On the summary page it shows the DNS servers of the ISP. I clicked on "Use these servers" (on the WAN1 setup) and entered DNS IP addresses on my network. It is ignoring them and still displaying the ISP's DNS servers.
