Certainly looks dodgy... this is mine

Network Destination        Netmask          Gateway       Interface  Metric
          0.0.0.0          0.0.0.0     192.168.10.1   192.168.10.99       20


Was that something set manually or via dhcp?  Try this command "ipconfig
/all", the should print out more info about the netwrok setting include dhcp
info if it is available.

WRT the other comments....

I'm confused, which machine is doing the masq?  The ADSL router or the
Ubuntu box?  If it's the router then I think my comment is correct still.
I'd certainly be trying to determine the internal ping issue first though.

Oooohh.. just checked my Kubuntu system...

bash> cat /proc/sys/net/ipv4/ip_forward
0

If memory serves me correctly, you need that set to 1 to make any sort of
network routing between interfaces functional.  Be worth checking that
directly rather than just looking the sysctl setup.  Also, is it a custom or
stock kernel... if it's custom, did you enable the options for that ?

Cheers,
Michael
