Many thanks. Though when I first tried this it didn't work, I took a
break to clean out my kernel (remove IPv6, and support for dozens of
things I don't have and will never use), and after recompiling, things
were up and running perfectly.

I now recall having had this problem previously, and remember that
flushing the routing table was what fixed it. I don't know why I
couldn't remember this when it mattered. 

Thanks for your help.
