Just grab any "how to build networks guide" and start using separate network numbering for separate networks and things will work out better. The fifth network card which points to your ISP device is smaller, but still inside those 4 others, which also is a bad choice. The way comp01 is set up on your first mail makes it equally valid for it to send out a packet on any of the 5 network cards to try to reach 192.168.1.254 for instance. This is of course not how you set up a box with 5 networks (even if "the network" is just a cable from comp1-re1 to comp2-re0) -- May the most significant bit of your life be positive.
