The connection sharing box provides DHCP.

Has ANYONE here actually read rfc3927? Link local means just that, link
local. Read the second paragraph of the abstract, and section 2.7 and
2.8, titled "Link-Local Packets Are Not Forwarded" and "Link-Local
Packets are Local".

Therefore, any device providing routing of any kind, MUST use something
else, namely DHCP.

This shit should Just Work, the only UI there should be is a checkbox to
disable "auto configuration" and set fixed settings.
