You need to spend some more time reading about TCP/IP in general and the
FAQ (http://www.openbsd.org/faq/index.html).  Be sure to also read up on
OpenBSD's Packet Filter (PF) (http://www.openbsd.org/faq/pf/index.html)
and Network Address Translation (NAT)
(http://www.openbsd.org/faq/pf/nat.html), which you will require,
if/since you are using a private address space.

Any specific reason why the subnet mask of your workstation is different
than that of sis0?

The gateway address on your workstation should be that of sis0...

I seriously doubt this is the correct gateway address... and if for some
unknown reason it is, there might be some confusion if using the same
/16 address space on your LAN.  I'd expect this address to be in the space... and dynamically provided to you.

What is this for?

Why two identical aliases?
