Issues with DNS of static DHCP hosts on LAN

    Perhaps this is a regression in a new build...I'm quite sure it used to work but now I'm having issues.

    I've set up static DHCP assignments but I can not access my computers by name on my LAN. Instead of accessing the computers on my LAN it goes out to the external DNS server like so:

    $ ping potato  #this is a computer name on my LAN
    PING ( 56(84) bytes of data.
    64 bytes from ( icmp_seq=1 ttl=54 time=93.8 ms
    64 bytes from ( icmp_seq=2 ttl=54 time=98.2 ms
    But I want 'potato' to go to

    In Basic >> DDNS I have "Use as DNS" checked for DDNS 1.
    In Basic >> DHCP/ARP/BW I have my hosts names defined with an IP address
    In Advanced >> DHCP/DNS I have "Use internal DNS" checked

    For debugging, if I ssh into my router then I can successfully ping my computers by name.

    I'm running tomato-E3000USB-NVRAM60K-1.28.0495.3MIPSR2-Toastman-RT-N-Ext.bin.

    Any help would be greatly appreciated.

    Perhaps I answered my own question. After an upgrade and a reconfiguration I was getting "unknown host" from my pings. I looked at /etc/dnsmasq.conf and the setting "dhcp-authoritative" stuck out since it will not answer to old leases. So I brought my network connection down and back up (to get a new lease) and now everything works. I guess this would have fixed itself after 1440 minutes (1 day) when the lease would have ran out.
