I have an ISP provided modem 192.168.1.1 with DHCP on, then a Linksys router LAN connected on with ip 192.168.16 also with DHCP.
Then a Synology 10.172.1.120 as it is connected to the Linksys router (10.172.1.1)
I want the Synology 10.172.1.120 to talk and see my outdoor the IP camera 192.168.1.15 that is connected to the ISP modem.
I cannot connect the camera to the router or the sinology to the modem, they need as they go to different rooms with internal cables. I don't want to set the Linksys router in bridge mode or turn off DCHP here. I enjoy the security and features of the Linksys.
I tried to turn off the DCHP on the ISP modem but I couldn't get online.
is there a way to forward ports or have some settings where devices in two different IP pools can see and talk to each other?
