In response to the current answer:
This would work if you wanted to segment off one PC. However some ISP’s only allow one IP and this situation would not work.

Not knowing much about your environment and what you want to accomplish I’ll make a simple recommendation, which involves three routers.

Assumed current setup:

ISP -----> Router1 -----> Network1

Proposed future setup:

ISP -----> Router1 ------> Router2 -----> Network1
                                 \-----> Router3 -----> Network2

Things to note:
Don’t share the same LAN address between any of the routers.

  • Router1 LAN IP 192.168.10.1
  • Router2 LAN IP 192.168.20.1
  • Router3 LAN IP 192.168.30.1

Network1 will not be able to access Network2 (I assume this is the goal) without some routing involved.
