    I have the latest Tomato build installed on my ASUS RT-16 router. I configured the router as WDS+AP client. The internet is working normal, the ping to gateway (my first router- is working as espected. Since I don't have WAN connection, I setup LAN connection as follows:
    DNS: (the IP of my first router - gateway)
    When I try to install the Optware software I encounter my problem. The wget is not working. So I try to ping the gateway - the ping succeed, then I try to ping yahoo.com - but here ping fail telling: host unknow.
    I try to setup the DNS from Advanced menu > DHCP> DNS, so I check :
    - Use received DNS with user-entered DNS
    - Use user-entered gateway if WAN is disabled
    Now the Ping command gives me the following message:
    Segmentation Fault.
    I check the logs but no error message appear.
    Can give me some hints ?

    I play a little with my router and check the following options:
    - Intercept DNS port
    - Use user-entered gateway if WAN is disabled

    Now the DNS is solved but I have the following message
    ping yahoo.com
    yahoo.com (71...)
    Network Unreachable
    Any idea?

    In routing page, add a static route gw as your default gateway.

    I think the better place to enter it is the "Default Gateway" field in Basic->Network.

    I already have this information as you can see:

    Router IP Address:	
    Subnet Mask:	
    Default Gateway:	
    Static DNS:  (IP:port)
    The WAN interface is disabled.

    I try all the combinations in Advanced > DHCP | DNS Server page but always I get these messages:

    root@unknown:/tmp/etc# ping yahoo.com
    Segmentation fault
    This is very annoying. :(

    P.S. I remove the DNS entry, saved the settings, insert address once again, saved the settings and ... ping is working.
    Thanks to all to your help.
    I think that this is a DNS bug.
