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.<br>
<br>
The radio doesn't multiplex anything.<br>
<br>
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 ...<br>
<br>
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.<span class="HOEnZb"><font color="#888888"><br>

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.<div><div class="h5"><br>

<div>OK, we can slap some extra security

What about the PtMP story? One of the advantages you mentioned
(Dean) was mobile access. Can it multiplex access somehow?<br>

The only "authentication" the radio has, are the
following:<br>
<ol>
<li>The radio can be set to only receive remote
transmissions that include a two-digit decimal code; <b>or</b></li>
<li>The radio can be set to only receive remote
transmissions that are addressed to the callsign

this setting).<br>

Any other authentication would have to be provided by a
router or firewall.<br>

We have a router at Snohomish County DEM with an extra
port that could be used for this. The subnet there is
<a href="tel:44.24.240.128" value="+14424240128" target="_blank">44.24.240.128</a>/28. We have another subnet of address
pairs set aside for router-to-router links. So as far
as networking goes, we could execute your plan. I
can't commend about the feasibility of any of the
other bits. <br>
