Please be more precise. What happens when connecting via ssh? Run ssh -v. Do
you get a timeout? Do you get a connection reset by peer? At which line does
it stop working. My glass ball is running overtime on this list.
Can you run tcpdump on all interfaces on your Compaq while you try to login?

I suggest you remove the generic default route - you've covered all
possibilities in other tables - unless there are more IP addresses on your
machine.
In that case, the problem is that ssh changes its TOS halfway during
connecting, causing packets that previously went out over, say eth0, to
suddenly go out over eth1, which may upset your local routing. Try ssh-ing
to one of the addresses for which a table exists.
Anyway, do the measurements. This setup is supposed to work just fine.

bert
