Several questions real quick here:
What kind of router is it? Can it do all the things that
you want it to from a firewalling standpoint? If so, I
wouldn't bother with the windows firewall, as it will slow
down traffic and have to be on all the time to do anything.
#2, In this type of configuration it wuld probably be
easier to do this as just a windows router configuration
rather than trying to bridge the networks. With the
subnet masks that you are setting it is going to get
confused and not transfer between the networks, as it
believes that everyone is in the same subnet. Mayhaps I
am confusing what it is you are trying to do.
Anyway, my suggestion:
St the subnet masks to 255.255.255.0 and then reestablish
your bridge, making sure that your 3rd octet is
different. If the bridge is not working, try just sharing
the connection to the router. It will still protect all
the machines behind it with the windows firewall and add
another layer of NAT. This will be problematic if you are
trying to supply services from the machines behind the
windows xp box. If that is the case I would just rig them
up to the router withour the windows xp interference as it
will intercept everything you are trying to do. Esp. as
windows xp Home edition was really not meant for that type
of work.
