|Thanks so much for weighing in on this, guys.|
I'm really perplexed now. It seems that I can administer only one Netgear router at a time.
I connected my computer directly to the outer router (router A) and enabled remote administration. I then moved my computer back to the inner router (router B). Hey presto! I can administer router A from within LAN B.
Fine. Now, I just want to check that I can still administer router B. I log out of the admin interface for router A, and attempt to access the admin interface for router B. It comes up with the welcome wizard, as if I had never used it before.
So then I log out of router B and attempt to again administer router A. Noooooo! it won't let me.
What on earth is going on? Could it be a cookie thing? I'm going to keep investigating this to see what other information I can gather. I'll check what cookies get saved.
