Started out that way, but it doesn't scale well, due to the storms, I'm
finding.  All my customers are behind NATed gateways, however, the network
between their router and the border router is all bridged.  But not for
long...

I'm also finding that the routing example put out by Karlnet is bogus.  For
instance, the indirect routes listed on the AP example couldn't have ever
been entered, as the target router(s) aren't in the subnet of the direct
routes.

 Any do and don'ts in routing using Karlnet, you've found, Martin?
