Hi, and thanks in advance for reading. I'm fairly capable, but a temporary replacement for a real tech guy.

The setup is as follows:
Internet in to one Qwest PK5000 wireless modem, which provides wireless internet access to two remote workstations.
One Netgear wired router, connected to the Qwest in order to provide internet access to a main workstation while segregating it from the less secure wireless network.

PC1 and PC2....(wireless)......|QWestModem|_____(wired)_____|NetgearRouter|______|mainPC|

With the Internet in to the QWest ^ and the printer in question connected to the mainPC ^

Neither the printer nor the main PC are wireless-capable. They are connected via USB.
As currently configured, the Qwest is assigning 192.168.0.xxx. The Netgear is assigning 192.168.5.xxx, with the only computer connected to it being the main PC with a static IP of 192.168.5.2.

My question is how best to set things up so that a remote PC can use the printer (through the Netgear network and main PC) with minimal security risks to the main PC (which is, after all, on it's own router for added security).
As I understand it, I could set the second router to a different range of IPs on the same subnet as the first, but that would negate the security advantage of the second network. The other options are DMZ, Port Forwarding, and VPN (as I understand it). The first two appear to open up some security risks, so I'm leaning towards the VPN.
As I said, my experience is limited and I'd appreciate the advice/instruction of those who really know what they are doing. Thanks again.

Cheers.
