Configuring the routers is not an option for me. I have permission to access
the office router and it is preferred that the home router be preconfigured and
not tampered with. Both the the home router and one of my home PCs will be
assigned fixed IP addresses on the office network.
For the sake of dicussion, let's keep it simple and not worry whether my other
private boxes will get access to the office net. Let's say only my one Linux
box will get access to the office net but, the problem at hand, is to make sure
that it can still be a node on my private network. I want to be able to share
resources between all my private nodes while allowing my Linux box to also be
on the office net.

This is exactly the case. Although the Linux bxo would have two addresses,
right? A 10.x.x.x address from the office and a 192.x.x.x from the home.

This uses IP aliasing correct? Is this a stable technology in 2.0 series
kernels? I can also boot a 2.1.97 kernel in case that matters.
BTW I have set up IP Masq on my private network already for Internet PPP
purposes. I assume that IP Alias and IP Masq can coexist.

The home net is using a legal Class C private net. The office net uses an
official registered address. I probably won't be accessing the internet
through the office connection but it might be interesting to know how to do it.
Using IP Masq, I am already able to access the internet through my ISP and have
all the boxes on my private net see the Internet. BTW ping does operate thru
masq quite nicely.
