What happens if, from one machine, while it's on the Internet (but
not in a VPN, for now) you try to ping the other one?
I'd expect this to be an issue that @home has seen before -- either
with the CyberSurfr or with their service.
I tried looking up specs on the Cybersurfr online, and found pages
over the past two years with pictures of different-looking devices.
SOME of those pages state that it can handle multiple IP addresses,
but others make no such claim. Reading between the lines a little,
it is claimed to support SNMP but to take no IP address of its own,
and I infer that it will therefore respond to a limited range of
queries directed to (one of) the connected IP(s). I can easily
imagine that such a function might, if defective, interfere with
correct operation of multiple IP addresses....
Another possibility is that while you've purchased a second IP
address, @home (or their local franchisee) still shows your line for
single-IP service.
