==DNS configuration on client(s)==
You have two choice:
#You [[Turning off DHCP|disable the DHCP]] on your HDA, and replace it with your router's DHCP. Don't forget to re-configure static IPs you had configured on your HDA into your router, and to [[RenewIP|renew the IP address]] on the client(s).
#You manually configure the DNS servers on your client computers to use your router as their DNS server (or any other DNS that is not your HDA). You HDA will continue to act as DHCP server, and will ask clients to use it as their DNS server, but as long as you can manually override that, you'll be fine.
