I connected pcwrt to a LAN port on my main router (subnet: 192.168.101.xxx), and am using it for all wireless connections (pcwrt subnet: 192.168.102.xxx) including my wireless printer. Main router wireless has been turned off, and I do not have “block literal ip addresses” checked on pcwrt. My PC is wired to my main router and can no longer connect to the wireless printer (PC->main->pcwrt->printer). Please advise how to connect across the subnet in this case.
Assume that the pcWRT router WAN side IP address is 192.168.101.100. And the printer IP address is: 192.168.102.200, printer port is 9100.
If you haven’t done it already, give the printer a name on the pcWRT router, for example, click the printer hostname on the Status page and name it printer.lan. The hostname should display in blue after you saved a name for the printer.
Next, go to the Network Settings page. In the Port Forwards section, click Add. Enter these values in the popup:
1. Name: Printer port forward (or anything meaningful)
2. Protocol: tcp
3. External Port: 9100
4. Internal Address: pick the printer (192.168.102.200)
5. Internal Port: 9100
Click OK, then Save.
On your PC, configure the printer to use the pcWRT router IP address (192.168.101.100) and port 9100.
