Howdy,

I usually have a wireless router connected directly to the
AT&T/Yahoo
DSL modem but last night I wanted to do some debugging so I plugged
my
laptop directly into the modem (after powering off the modem, etc.).

The values I got back from DHCP not only don't make sense, they
didn't
work in FreeBSD at all. Dual-booting to Windows showed that the
values
I saw from DHCP were "correct," and somehow they managed to work.
Taking a closer look at the router after I plugged it back in showed
the same.

        Dhcp Enabled. . . . . . . . . . . : Yes
        Autoconfiguration Enabled . . . . : Yes
        IP Address. . . . . . . . . . . . : 76.212.147.xxx
        Subnet Mask . . . . . . . . . . . : 255.255.0.0
        Default Gateway . . . . . . . . . : 151.164.184.xxx
huh?

only way this could work would be if it was marked as "point to point"
I think..
That could be a primary IP address on an interface on which your 76
address is a sub interface.

Can you specify what you mean by 'that'?

The interface will do proxy-arp when a
traffic request comes in.  Or something else!  I'm not sure if this will
work, but you could actually hard code your default gateway with a
-hopcount 2 (or higher) and see if that works.  I've not tried it on a
live machine.  Something like route add default 151.164.184.xxx
-hopcount 5.  You may have to delete the DHCP-assigned entry first.

Ah, I didn't know about -hopcount, thanks. There was no default route
installed at all when I booted. I tried 'route add default 151...'
even though I was sure it wouldn't work, and I was not disappointed.

Doug



also not sure if you can add a -iface argument to make your default route include the correct interface .
