I think that the features that you are looking for are going to available
only in the top end equipment - most firewalls assume that you will have
three networks at most the untrusted network ie Internet, trusted internal
network that you would put your machines on and DMZ (Demilatrised zone)
where you put servers that can be accessed from the untrusted network as
well as your internal network - a business webserver. The computers in the
DMZ cannot access the machines in the internal network. If a computer in the
DMZ is hacked then they cant reach the other machines.
The setup you are looking for is a more specialised setup. You could make
your own machine to do this with four seperate network cards and configure
the software yourself - lots of work and fun.
Most of the shelf routers that have four ports are just a router with four
port switch all in one unit. Some router just have one port that you have to
wire to a seperate switch to get more ports.
The only way that you might be able to do this is port forwarding where a
request to a web page goes to a particular machine - with other services
going to seperate machines.
