Network Bridge flooding our network with traffic and broadcasts
Posted on 2004-11-23
Our network is connected via bridge to another local government network and we have no control of the bridging routers.
The other network is now flooding our network with broadcasts and we can see their network and they can see ours.
I want to be able to stop this, the broadcasts, and only allow certain ports through.
Our network is 10.2.0.0 and the other network is 10.100.0.0 and 10.6.0.0.
Bearing in mind i have no control of the Bridge and the other network cannot make any changes, what is the best way to do inline filtering/firewall ?
I did consider a linux firewall with 2 network cards on a spare pc, but this is different from a normal configuration as both network cards would need to have 10.2.0.0 i.p. addresses.
Any thoughts ?
