We're not trying to link Base 1 to Base 2 here. They're already linked
through our very-large Motorola Canopy backbone. We simply want redundancy
on the Satellite by having it have two links to the Internet (Base 1
primary, Base 2 failover).
We set the Base 2 to Ch 1, ID 1 and did the same on the Sat - now it links,
but does not communicate.

Well Jayson,
All I can say is that if you dont appriciate the help you get then i have
nothing for you. All the CRAP I was giving you was years of experience in
running a successful WISP using Karlnet. If you wanna run your setup the
way you do, thats fine with me.
BTW: read http://www.wep802.com/knet_TC_01.htm and see why your current
setup DOES NOT WORK, and why i suggested 4200.
