It was the argument values you're giving to those functions that I was
particularly interested in, but I think you've already got to the bottom
of the problem so not really necessary anymore.

Should be fine, but I think you should be able to set eth1 as the
default from the beginning.

I'd be interested in why DHCP server doesn't work on a non-default
interface.  Can you explain why?  If it did you could just have eth1 as
the default interface to start with.
