[HamWAN PSDR] 44.x.x.x HamWAN network at Paine

[Dean Gibson AE7Q]

I had to Google to find out what P2MP was, but in my VERY brief Google 
education on the subject, I don't think it applies.

The radio doesn't multiplex anything.

The consumer-grade routers I own (Linksys BEFSR41, Netgear WGT624v2) 
seem to have no way to turn off NAT.  dd-wrt is not possible with the 
BEFSR41;  it is "work-in-progress" for the WGT624v2.  NAT seems to make 
routing issues a little more complex to think through.  Both routers 
have the ability to specify a "DMZ host", but I think that just turns on 
universal NAT to that host.  Both routers have the capability of 
manually adding entries to a static routing table, but I don't know if 
that skips over the NAT.  If we have to have NAT, it seems to me that 
the best way to set up the router is with the radio connected to the LAN 
side (with whatever private IP address we want), and have the WAN side 
connected to the 44.x.x.x network. That allows incoming (ie, via the 
radio)  packets to go wherever they can and responses to come back; 
whereas orienting the router the other way (unless we use the "DMZ host" 
feature) doesn't.  I suppose I could donate one of my (very) elderly 
(2005) Dell PowerEdge 1650 1U servers to the effort, but that seems like 
a bit of overkill ...

What I think would be a good idea is to meet and discuss this 
face-to-face (pretty much anytime) with diagrams, rather than shoveling 
eMails back and forth.  Scott, if your schedule permits, you are more 
than welcome.

ps: Scott, I plan to come to the DEM on Tuesday to start on this, unless 
you're not going to be there, or other conditions (like ongoing slide 
work) make it a bad idea.
