Is this a new connection or one an existing connection that has broken?

Hmmm I think I'm missing something. 192.168.1.3:192.168.1.99 both seem to be
on the same network.

I would imagine that the scenario should be something like:
home network 192.168.2.0
office network 192.168.1.0

Some machine on the home network connects into somemachine on the office
network.  The PPP link uses the ethernet IP's of each machine involved.
The machine on the office network acts as a gateway to the home
network and the home machine acts as a gateway for the office network.
Can't realyy see the need to use proxyarp.

Now what did I miss?

Yours Tony
