That's what I thought. Now they tell me that their routers (which pass
routing info via rip) can tell the presence of hosts on the other side of
my Linux router, which is using static routes, and that's the reason that
they claim I can't even get into their network.

This is the way that diald seems to want to work.

220.127.116.11 (the modem) is an accessible host. This weekend I'll be
building a 486/25 to be 18.104.22.168, which probably won't be available
to the internet until I get the routing right, but you could telnet to
22.214.171.124 and then telnet to 126.96.36.199, and then do whatever
testing/snooping came to mind.
