That puts your local addresses within the same (sub)net as your remote
system. The remote LAN will have hosts that don't know how to get to
your local systems unless you are advertising the subnet via RIPv2 or
similar.....

The office machines will need to *know* that the "home addresses" are not
local - that can only be achieved by advertising the sub-net-route locally
or allowing the "office" P50 to proxy for those addresses...it's an
unusual setup really...

Those addresses are the only ones that will know *where* your home PC
is topologically with respect to your network....

The router knows where things are based on it's configuration...but the NT
server would not know that the remote IPs are accessible only via the
router...i.e. it doesn't know it needs a 'router' to get to them....

>Where am I going wrong in the IP addresses or is it something else?

Either changing the IP addresses to avoid this overlap, or set the office
Pipeline to send routing updates (which might still not work.....another
subject), or to proxy for the remote network.
