Can I have two Ethernet cards on one PC and have access to two different networks, without the two seeing each other? Does that also put the two networks in any security dangers with hackers going in one server and running into the other?
The ideal way to do this is to put the two of them on differently numbered subnets -- 192.168.1.x vs. 192.168.0.x, for instance, each with their own subnet mask. Also, unless the machine is actually serving as a router between the two subnets, it's not that easy for it to be a security hazard unless there is active file sharing or something of the like taking place.
