Question : Problem: Network Topograpy to allow three seperate networks share one network printer

Current Setup:

WAN -
   5PORT SWITCH - DSL Modem (Transparent Bridge Mode)
       WRT54G  -  192.168.31.1  (each has static IP from ISP)
       WRT54G  -  192.168.32.1  (each has static IP from ISP)
       WRT54G  -  192.168.33.1  (each has static IP from ISP)

Each device will support seperate work groups.  They would all like to share a Xerox high volume print / scan / fax device.

Answer : Problem: Network Topograpy to allow three seperate networks share one network printer

the easiest is to buy a cheap layer 3 switch for about $200-$300  or less. as an adiitional benefit it'll allow you to do lots of other things


as of your idea, if I understand you correctly, you can't have same interface in multiple broadcast networks
