Thank you to all who put up with my very many stupid questions!
The old (NAT only) rt-314 router is still alive and well. After many hours
of peeking and poking, it is now fully happy and ready for "spare" work
should my current router takes a powder.
What was wrong?
-The power brick was dead! Should have been outputting 12.0Vdc. Was
outputting 0.774Vdc.
(good thing I saved the original wall-wort!)
-3 of my LAN client's web browsers were locked down too far to allow logon
interchange with the router! Found this today with the client connected to
the gw_router via telnet! Duh.... now fixed.
-My own knowledge of proper subnet business.
All in all, an interesting problem to solve, and, I've saved a really good
"old" gw_router from the bin.
Now, I can clean up the workspace and get back to FreeNAS!
BTW, my conversion to full GBit-over-copper is complete. It works; and
here, it is a noticeable improvement. Glad I waited 5 years to do the move.
Will never go back to 100baseT unless under duress, or, cuz "that's all I
can do!" It is all good.
Thank you all,
Duncan
