I would say that you should get it working on your LAN first, then see 
about moving it off site.  Assuming you're on a 10/24 LAN:

10.0.0.2 - your computer
10.0.0.3 - the slug (uses port 1194 for openvpn)

10.0.1.2 - your computer's VPN IP (the tun device)
10.0.1.3 - the slug's VPN IP (tun device)

Now if you can connect openvpn and ping/rsync/ssh/whatever from your 
computer to 10.0.1.3 you're all done.  When you move the slug you change 
it from 10.0.0.3 to the new LAN (and change the VPN config too).

The firewall rule is simple, just port 1194 and NAT if necessary.

You might want to pick something random for the VPN network (10.0.1.0 
above).  It can't match any of the other networks you use if you want to 
keep your sanity.
