the bridge thing is not possible.. the network is too big.. 300 machines.. with over 30 switches (only one of them is manageable) :( Basically I want to deny ethertype 0800 (IPv4) packets for that LAN. The only solution I thought of was to have a linux machine in this LAN that has all the possible IP addresses set on its interface.
Look, we can't help you until you explain the problem
WHY is it not possible to have a bridge? This only requires two network cards?
I want to block the traffic between _ANY_ 2 of the machines in the network.
How about giving them a netmask of /32 instead of /24 (or whatever you have) so that they only see themselves in the same network and then giving them a static route to the default gw (since it is outside of the /32).
Then you can block all inter-client traffic at that single default gateway (or one hop "in front" of it, seen from the clients)
I don't have access to those machines :-) they use internet via different ehternet protocol (PPPoE)
If you don't have access to those machines, you need to do "something" where you have access which presumeably is at the switches. But that means you either need to replace those with smart ones (which can also be a linux box with many nics or multi-port nics) or basically put a linux box with 2 nics in between the cable from the client and the switch port. Either way, it's not gonna be cheap and possibly isn't feasible at all. I see no easier solution if you cannot control/trust the client systems.
