Background:
I have two RG6 cables run to every room in my house, but currently only one is used and connected (cbl1) to my ISP and cable provider. I have two routers and currently have my main router (rtr1) connected to the ISP via DHCP. The second router (rtr2) has COAX WAN disabled and I have it bridged to the home network and acting as a DHCP relay (so that devices connected to it get their IP from rtr1).
I'd like to use the untouched RG6 (cbl2) to create a physically isolated network, and then connect them with WAN-LAN ethernet so that everything on rtr2 (cbl2) network will talk internally without traffic on cbl1, but still get everything outside (internet) via gateway to rtr1 (and ISP).
Here's what I think I need to do to accomplish this:
rtr1 configuration (Network1):
WAN (broadband coax) IP: (from ISP)
WAN DNS: (from ISP)
WAN IP Distro: Disabled
rtr1 IP (LAN or Home Network): 192.168.1.1
rtr1 subnet: 255.255.255.0
rtr1 DHCP Server: Yes (192.168.1.10 - 192.168.1.50)
rtr1 DNS: 0.0.0.0
rtr2 config (Network2):
WAN rtr2 IP: 192.168.1.2 (Network1 IP address)
WAN subnet: 255.255.255.0 (?)
WAN gateway: 192.168.1.1 (rtr1 IP address)
WAN DNS: 0.0.0.0
rtr2 IP(Home Network): 192.168.2.1
rtr2 subnet: 255.255.255.0
rtr2 DCHP server: Yes (192.168.2.10 - 192.168.2.50) (DIFFERENT subnet than rtr1)
rtr2 DNS: 0.0.0.0 (so will use gateway DNS I think)
Firewall: OFF (because rtr1 firewall ON and this router can only talk to "outside" through router1)
With this config rtr2 WAN should see internet access and serve all connected devices on the .2.x network I think.
Couple questions:
1) Subnet in particular, but does this configuration for both routers look like it would work?
2) Will this config work to isolate all internal network traffic by devices connected to router 2 (rtr2), so that say copying files from device 1 to device 2 (connected to rtr2) would only show up on cable 2 (cbl2) and not be passed over to router 1/cable 1/ISP?
3) Is this worth the effort? It seems to me that having a cable with no other signals (analog and/or digital) would make the network much quicker, and having all the traffic off the ISP connected line would make it more secure. That said, I'm not sure if it will do what I intend.
4) Will this cause any subtle problems (gaming/streaming/etc) with internet access on the isolated network (192.168.2.x)?
